i think the equation would be :
4+ ( - 3 ) =
so that would probably be back to four if it was four plus minus three you would add three then minus it which would make it FOUR.. ( but im not completely sure so don't just depend on this )
-4 - 3 = -7
7
-1
Zero
-4 + -3 = -7
-7
plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
The answer is 0.
Positive 3 plus negative 5 minus negative 2 minus positive 4 is equal to -4.
4 - 5 + (-2) = -3
- 4 +- 3 = -7
4
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
minus 6, plus 3, minus 6, plus 3...
