Repost: Need Help Finishing My Math Game!
Here's my problem, I need to make it so there are no negative numbers or any non-whole numbers at the answers in my game. My game is working as intended so far but I can't figure out how to stop the game from making the answer negative or a fraction (i.e: 1-9=-8 or 4/8=.5).
I've already got some help and implemented the advice but I can't get it to work properly for division problems. I've got subtraction working though. Here's the link: https://scratch.mit.edu/projects/287542937/

Work the division backwards for now. Multiply two numbers to get the product. Set the dividend to the product. Set the divisor to one of the numbers you used to multiply earlier. Then set the quotient to the other you multiplied. There are better ways but for now, working backwards should help.
num1 = some number
num2 = some number
product = num1 * num2
dividend = product
divisor = num1
quotient = num2
num1 = some number
num2 = some number
product = num1 * num2
dividend = product
divisor = num1
quotient = num2

You have the Ask script inside the ELSE, it should be inside the IF.
Having said that, it still won't work as it is. Deck had the right idea, get rid of the repeat loop around SET value 1 and SET value 2 and add
then set value2 to say 7
then you set value1 to value1 * value2 = 5 * 7 = 35
then you ask what is value1 / value2 = 35 / 7 = 5

An efficient way to check if a number is negative or a fraction:
if <not <((Number) / ([abs v] of (round (number)))) = [1]>>then
end
when green flag clicked
forever
Be awesome!
