-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.
Yes.example: -1+(-1)=-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.
-1
The sum of -1/15 and -3/5 is -2/3
negative three
-4 + -5 + -2 + -1 = -12 (negative 12).
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
negative 2
The sum of -1 and -2 is -3.
Yes.example: -1+(-1)=-2
The total sum is -12 or negative twelve.
-2 + 1 = -1
negative -1/2+-1/2 = -1
9 to negative 2 = 1/9 to plus 2 = 1/81
