Last week’s high light:

* the level (order) of operations that you must do is below:

Bracket ( ) do all operations inside the brackets first.

Exponent and Root then do any Exponent and Root operations, if you have both Exponent and Root do from the LEFT to the RIGHT.

Additional and Subtraction then do Additional and Subtraction operations, if you have both of them do from the LEFT to the RIGHT.

For example: 40 – 2 + 3

Right answer: = 38 + 3 = 41 (do from Left to Right)

Wrong answer: =40 – 5 = 35

another example: 3 x 2 / 2 x 3

which answer is right???

Answer Option 1: doing multiplications first

6 / 6 = 1

Answer Option 2: doing division first

= 3 x 1 x 3 = 9

Answer Option 3: doing from left to right because Division and Multiplication have same level

= 6 / 2 x 3 = 3 x 3 = 9
