It's a pleasure to have you here in our class for this year! One thing you'll need to know for our Mathematics class is BIDMAS. BIDMAS is called the order of operations, which is how you'll be answering math problems. BIDMAS is short for Brackets, Indices, Division, Multiplication, Addition and Subtraction. This is the order that you will go through when you solve a math equation. For example, 3 x (3 + 7) - 4 2 /2. You'll first do the brackets.
= 3 x 10 - 42/2.
Then the Indices.
= 3 x 10 - 16/2
Since you have division and multiplication, you will do it from left to right.
= 30 - 16/2
= 30 - 8
Since you do not have any addition, you will do substraction next.
= 22
There you go! If you did it in order, you will get a different answer.
3x3 = 9 + 7 = 16 - 4 = 12 x 12 = 144/2 = 12...
(Hope I was right)
