Hidden? Well really it is maybe a short-cut: \(-3-4=(-1)(3+4)=(-1)(7)=-7\). Do you see the logic there?Hi guys, when combining negative like terms such as -3x -4x will give -7x. Does that mean that there's a hidden + between them?
A better way to think of it is that we define subtraction as addition of the opposite (negative): a - b means a + (-b).Hi guys, when combining negative like terms such as -3x -4x will give -7x. Does that mean that there's a hidden + between them?
It's good to watch things be cleared.Thanks guys, that's cleared things up for me
