Order of Operations

B- brackets


E- exponents


D- division


M- multiplication


A- addition


S- subtraction



eg. 2+ 3 x 4= 1. So first you look if theirs brackets but theirs no brackets so you go to the next one.


2 + 3x4= 12 2. So now you look if theres a exponent but theirs none too so you just move on.


2 + 12 =12 3. Next you look for a multiplication or division their is multiplication so you do that one 3x4


4. Now you bring down 2 and + then you look if there is addition or subtraction theres addtion so you do that 12 +2 equals14.

thats how you do it.


here is a picture to show you.







now here is a video to show you.

1.7 + 6 divided by 2 = 3
1.7 + 3 = 4.7
