What is the sum of a number and - 2 / 11 equal to - 1 / 3? (list and calculate) -2 minus the sum of - 1 / 3 and 1 / 2, what is the difference? (list and calculate)

-2-(-1/3+1/2)=-13/6

3 + 1 equals minus 2 and does not change the number
3 + 1 plus a matchstick equals minus 2

I don't know how many matchsticks can be moved. 3-1 = 2 - 3 + 1 = - 2

If the difference between two numbers equals 11 and the product equals minus 28, then the two numbers are equal

7 and - 4
