Answer:
GEMDAS is the rule that can be used to simplify or evaluate complicated numerical expressions with more than one binary operation.
Very simply way to remember GEMDAS rule :
G ---> Grouping (Parentheses)
E ----> Exponent
M ----> Multiply
D ----> Divide
A ----> Add
S ----> Subtract
IMPORTANT;
1. In a particular simplification, if you have both multiplication and division, do the operations one by one in the order from left to right.
2. Division does not always come before multiplication. We have to do one by one in the order from left to right.
3. In a particular simplification, if you have both addition and subtraction, do the operations one by one in the order from left to right.
Examples :
12 ÷ 3 x 5 = 4 x 5 = 20
13 - 5 + 9 = 8 + 9 = 17
