Most of us hate math. We don't want to go up to the board to answer a question. We don't want to feel like an idiot when we can't keep up with the rest of the class. And we certainly don't want to be tested on things we might never use again in the future. Of course, it's a subject that we have to learn if we want to receive our diploma. In order to make your school life a little easier, here are a few math hacks that'll help you out with the little things, so you can spend more time focusing on the big things:
1. Multiply 9
You should've learned your multiplication tables back when you were in elementary school, but sometimes it'll slip your mind. If you have trouble multiplying nines, then all you have to do is use your fingers. If you're multiplying nine by five, put down your fifth finger and see what's left. Four fingers on the left hand and five on the right? That means the answer is forty-five.
