This is how you do the hopscotch (PEMDAS). First put your feet together and jump by saying Parentheses!then put your feet together again and jump by saying Exponents!Then put your feet apart and jump by saying Multiplication and Division from left to right.Then jump with your feet apart and say Addition and Subtraction from left to right.Do all the hopscotch step with hand movements.

Parentheses

The symbol of parentheses Is this ( ) and it stands for Please.

Exponents

It is multiplying the number like 3x3x3 which is 27. So the square root for that is 3.

Multiplication and division from left to right

Like I said you do it from left to right like 2x4+(4/2) you do division first then the multiplication.

Addition and Subtraction from left to right

Like I said you do the addition and subtraction from left to right.Just like the multiplication and division from left to right but with addition and subtraction.

That is all about PEMDAS
