-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.

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.
