-7 -(-2) = (-1x7)-(-1 x2) =-1x(7-2) =-1x5 = -5
Okay. that is overcomplicated.
Think of it this way:
If you have -7 and you're tanking away -2 of that, just take it away. Naturally, with subtraction subtract the sign and add like terms.
Like this:
(-7) - (-2) ===> (-7) + 2
See? When you do subtracting negatives, it's like adding a positive.
Hopefully you will never have problems with this, it's simple when you have the hang of it.

An equation where Y = -7
minus a negative is plus a positive so something like -6 - -7=1 because its the same as-6 + +7
7 times minus 2 =
no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2
-2 is greater than -7 because it is the closest to zero and -7 is colder than -2
