What is 1 plus negative 2?

Answer 1

3

Answer 2

When you add 1 and -2, you are essentially combining a positive integer with a negative integer. In this case, the negative integer (-2) is greater in magnitude than the positive integer (1). When you add them together, you subtract the smaller number from the larger number and give the result the sign of the larger number. So, 1 + (-2) equals -1.

Answer 3

-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.

Answer 4

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.
