What is PEDMAS rule?
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. PEDMAS: Parentheses, Exponents, Division and Multiplication(from left to right), Addition and Subtraction (from left to right).
According to the question
Charlene decided to ride her bike from her home to visit her friend Danny.
Three miles away from home, her bike got a flat tire and she had to walk the remaining two miles to Danny's home.
She could not repair the tire and had to walk all the way back home.
= 2 miles going + 5 miles returning - 3 miles on bike
By using PEDMAS rule, first we have to add 2 miles and 5 miles
= 7 miles total walking - 3 miles on bike
By using PEDMAS rule, next operation of order is to subtract
= 4 miles excess of walking than biking
Hence, Charlene walk 4 miles excess of walking than biking.
