-2 Same as plus 3 minus 5. If you don't believe it, Put +10 in front and take it away afterwards : 10-5+3-10 is 8-10 is -2. If you keep the sign in front of each number, then you can switch around: (-5)+(+3) is (+3)+(-5) is (-2)
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
n-10+(9n-3)=10n-13
The equation N-10 plus 9N-e equals 10N-3. This is a math problem.

9n + 12y = 3(3n + 4y)
11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57
-7 plus 10 is the same as 10 minus 7, which is 3.

it is 10n
Strangely enough, it is 9n + 1 for n = 1, 2, 3, ...
2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10
