1 plus negative 10 is equal to -9.
The sum of -9 and -1 is -10.
8 and 1/10
It's 9. Hope I helped! :)
9+10=21
4x = -36 x = -9
-9 - (-5) = -4 You know like you do: -10 - 9 is the same as -10 + -9 that seems easier ^^ The same rules apply to -9 - -5. When you change the subtraction sign to a plus, you have to make the negative five a positive.
9 + 9 + 10 + 10 = 38
9 + (-8) = 1
Negative 9
