Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1

-2 + 1 = -1

When you multiply a negative number by a positive number then the product is always negative. When you multiply a positive number by a negative number then the product is always negative. ( - 2 ) ( + 3 ) = - 6 ( - 4 ) ( 1 ) = - 4 ( - 1 ) 2 = - 2 ( + 2 ) ( - 2 ) = - 4 ( 3 ) ( - 2 ) = - 6 4 ( - 2 ) = - 8

Yes.example: -1+(-1)=-2

negative -1/2+-1/2 = -1

9 to negative 2 = 1/9 to plus 2 = 1/81

-3 + -2 + 4 = -1

1 plus negative 2 is -1, because adding negative numbers makes a number lower. And vice versa, meaning that subtracting a negative number adds to the value.

It wil be a negative answer as for example -1+(-1) = -2

3 raised to negative 2 would be -9 plus 6 to the negative 1 which is -6 so -9+-6=-15

Negative 3 + one is negative 2.

-n+-n=-2n so -1+-1=-2. In simple terms a negative plus a negative eqauls a negative. You can just add the numbers as if they are positive and then add a negative sign to the answer.

One.

-1+3=2

-2 + 1 = -1

-2*(-2)2 + 0*(-2) + 9 = -2*4 + 9 = -8 + 9 = 1

3 Because -2+1= -1 and -1+4= 3 therefore your answer is 3.

2

-1+2=1 If you have a negative number and a positive number subtract them. If the negative number is higher than the other number then it is negative. To change the expression but keep the answer the same you can do 2-1=1. Take out the addition sign and switch the numbers.
