(I'm not sure how log is applicable) @asianrandy -- here's an example that will perhaps help you figure out how to do addition. var item1 : real := 55.99 var item2 : real := 5.99 put "The total of 2 items is: ", item1 + item2 ;) ----------------------------------- asianrandy Wed Sep 24, 2008 12:05 pm Re: i need help with this math crap very badly ----------------------------------- % This program will print out invoices to send to people with their orders locate (1, 25) put "AUTOMATIC MARKING MACHINE" var name : string put "Customer Name: " locate (2, 15) get name var total : real := 0 var product : int loop put "number of items ordered (1=Computer, 2=computer2, 3=computer3, 4=computer4, 5=postage and handling, 6=quit): " .. get product if product = 1 then total := total + 55.95 elsif product = 2 then total := total + 111.90 elsif product = 3 then total := total + 167.85 elsif product = 4 then total := total + 223.8 elsif product = 5 then total := total + 30.00 elsif product = 6 then exit end if % The phrase "total : 0 :2" outputs total to two decimal places put "The running total is $", total : 0 : 2 end loop put "Final total = $", total : 0 : 2 this is what i got but l'm close to it ----------------------------------- asianrandy Wed Sep 24, 2008 12:07 pm Re: i need help with this math crap very badly ----------------------------------- can you give me some tips on turing on addition ----------------------------------- Insectoid Wed Sep 24, 2008 12:12 pm RE:i need help with this math crap very badly ----------------------------------- Use another counter to get number of items, then, at the end, cls and print everything the way you want. ----------------------------------- asianrandy Wed Sep 24, 2008 12:38 pm Re: i need help with this math crap very badly ----------------------------------- i need help where to put the 5%gst and 8%pst and what the code for it % This program will print out invoices to send to people with their orders locate (1, 25) put "AUTOMATIC MARKING MACHINE" var name : string put "Customer Name: " locate (2, 15) get name put "Total of items ordered " .. var number : string get number var total : real := 0 var product : int loop put "Total Cost of items: " .. get product if product = 1 then total := total + 55.95 elsif product = 2 then total := total + 111.90 elsif product = 3 then total := total + 167.85 elsif product = 4 then total := total + 223.8 elsif product = 5 then total := total + 30.00 elsif product = 6 then exit end if % The phrase "total : 0 :2" outputs total to two decimal places put "Total Cost of items: $", total : 0 : 2 end loop put "6% GST:" put "Final total = $", total : 0 : ----------------------------------- asianrandy Wed Sep 24, 2008 12:39 pm Re: i need help with this math crap very badly ----------------------------------- i dont no how to fix the problem ----------------------------------- Euphoracle Wed Sep 24, 2008 2:29 pm RE:i need help with this math crap very badly ----------------------------------- Multiplication in turing is done using an multiplication operator in the form of an asterisk: put "3 x 5 = ", (3 * 5) : 0 Remember, however, that expressing a percentage as a decimal requires you to first divide it by 100. The reasoning for this is the fact that a decimal totals up to 1 (0.5 + 0.5 = 1), whereas percentages total up to 100 (50% + 50% = 100%). Knowing this, you should be able to calculate 6% GST of the total cost of the items. ----------------------------------- asianrandy Wed Sep 24, 2008 3:08 pm Re: i need help with this math crap very badly ----------------------------------- Automatic marking machine cost: $55.99 customer name : nameless business name : nameless number of items ordered: 4 total cost of items : 223.80 postage and handling: 30.00 subtotal: 253.80 5% GST: 15.23 8% PST: 20.30 finall total: 289.33 so far i got is this var name : string put "Customer Name: " locate (1, 15) get name var items : string put "Number of items ordered: " get items var total : real := 0 var product : int loop get product if product = 1 then total := total + 55.95 elsif product = 2 then total := total + 111.90 elsif product = 3 then total := total + 167.85 elsif product = 4 then total := total + 223.8 elsif product = 5 then total := total + 30.00 elsif product = 6 then exit end if % The phrase "total : 0 :2" outputs total to two decimal places put "Total Cost of items: $", total : 0 : 2 end loop put "Final total = $", total : 0 : 2 [/size] customer name: myname number of items ordered: 4 l'm right to get any number i want and get whatever i want too add $ 30.00 then add the subtotal then calculate the subtotal to get the gst and pst and get the final total. I have no idea what to do. The Introduction to programming book doesn't tell you what l'm doing. it quite confusing. ----------------------------------- Insectoid Wed Sep 24, 2008 4:40 pm RE:i need help with this math crap very badly ----------------------------------- The introduction to programing (in Turing??) book is utter crap. I assume you're talking about the holtsoft one? First, you need to use code tags. they work like this: [code]paste code here[/code]. This makes it easier for us to read and then find the problem. Second, I am afraid that if this simple program is this complicated for you, you will not get far in the field. I'm not trying to be mean or anything, but it's the truth. On to helping! Okay, you are asking the user for the number of items they are ordering. This is bad. Instead, every time they add to the order, add one to 'items' (which has to be an int, you've declared it as a string) so this: get product if product = 1 then total := total + 55.95 end if becomes this: get product if product = 1 then total += 59.95 %a quick way of saying foo := foo + 1) items += 1 end if It only takes one extra line and streamlines the user's experience. ----------------------------------- S_Grimm Thu Sep 25, 2008 8:38 am RE:i need help with this math crap very badly ----------------------------------- insectoid is right. You need a pile of "if" statements (One for each product) and then put them in his code (so instead of "if product = 1 then", you need "if product = 2", "if product = 3", etc..) ----------------------------------- SNIPERDUDE Thu Sep 25, 2008 2:44 pm RE:i need help with this math crap very badly ----------------------------------- Or a Case Statement. ----------------------------------- asianrandy Thu Sep 25, 2008 9:21 pm Re: i need help with this math crap very badly ----------------------------------- var total : real := 0 var product : int loop put "number of items ordered (1=Computer, 2=computer2, 3=computer3, 4=computer4, 5=postage and handling, 6=quit): " .. get product if product = 1 then total += 59.95 items += 1 end if 1 becomes an error and i dont no why. ----------------------------------- [Gandalf] Thu Sep 25, 2008 9:38 pm RE:i need help with this math crap very badly ----------------------------------- Please use end loop at the end of the program.

You can't preform math on text. What you're looking for is to make it an int or nat variable. As for the rest of your program, you need to think about it logically. My best interpretation of your program is that you're wanting the user to select what he wants to buy, and the price is added to a total. You're probably going to want to wait to tell the user how many items they ordered until the end of the program, or atleast until after they've ordered all their products. ----------------------------------- Insectoid Fri Sep 26, 2008 6:45 pm RE:i need help with this math crap very badly ----------------------------------- You can have nat variables in Turing?
