Question

4-(-3)+1
2-2÷(-2)
There is supposed to be a fraction line in between the sets of numbers. I do not know how to make my computer underline this.

Answer 1

We use / to indicate division, which of course is the fraction bar, and placing the expression to be divided in brackets
so yours would be

[4 - (-3) + 1]/[2 - 2÷(-2)]
= 8/3

I put (4 - (-3) + 1)/((2 - 2/(-2))
into the Google window and got

Google doesn't like the square brackets, had to change them
