Question

Why do we need math formulas?

Answer 1

because the formulas can help us to solve the problems. so the formulas is necessary for maths

Answer 2

Math formulas, which are equations that show us how to work something out, tell us exactly what we need to do to solve a particular problem. If we didn't use formulas, then we would have to do all the work that led up to the formula ourselves to find our answer. For example, if we wanted to find the volume of a box, we could either use the formula for the volume of a box, V = l * w * h, or we could use our basics and spend quite a bit of time to figure out that to find the volume of a box, we need to multiply its length, width, and height. Either way we go about it, the formula finds its way in. We can either use it to help us, or we can do things the hard way. I think letting formulas help us is the way to go.
