Chapter 1: Q1. (page 8)

Describe how will you evaluate the expression $a + b [(c + d) \div e]$ given values for $a, b, c, d,$ and $e$

Short Answer

Expert verified

Follow the following steps:

To simplify parentheses add $c$ with $d$
Divide resultant with $e$
Then multiply it by $b$
Finally add $a$ to get resultant value

Step by step solution

- Follow order for simplification

Firstly, evaluate expression inside parentheses, brackets, braces and fraction

Then simplify powers

Then do multiplication and/or division from left to right

Then do add and/or subtract from left to right

- Simplify bracket

$[(c + d) \div e]$

Since, parentheses is inside bracket so first simplify it by adding $c and d$ then divide resultant by $e$

-Multiply resultant of bracket with b then add a

$a + b [(c + d) \div e] = a + \underset{}{\underset{⏟}{b \times [(c + d) \div e]}}$

Thus, given expression will be evaluated by following steps

To simplify parentheses add $c$ with $d$
Divide resultant with $e$
Then multiply it by $b$
Finally add $a$ to get resultant value
