During this lesson we learnt the affect of bedmas when using algebra equations.


 * B E D M A S**

B- Brackets E- Exponents (includes to the power of) D- Division M- Multiplication A- Addition S- Subtraction.

Why do we use Bedmas or bema ? you use bedmas because if your doing an equation that is the order you follow in order to solve the problem. for example : x - 10 = 16 divide by two, its almost as if the brackets are there anyway. Class Question : Does it matter weather you have brackets or not?

To undo a power or a square do the squareroot.

An equation using Bedmas -

X - 10 divide by 2 = (you do the 10 divide by 2 first)

An equation not using Bedmas,
