Why does -7 - (-4) have the same results as -7 + 4?
For someone else
-7-(-4) is the same result as -7+4 because any negative added to a negative sign will be a positive. When adding mainly like this it is super easier to automatically change the -(-4) to a positive then just do 7-4 and you will get 3 then just add the negative sign
