$138$ $138$

Order of operations:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

First parentheses:

$(4 + 4^{2})$ $(4+4^2)$ is the only statement in parentheses

In here we do exponents:

$4 + 16$ $4+16$

Then addition:

$20$ $20$

So back to our original problem:

$8 + 100 + 10 + 20$ $8+100+10+20$

The only operation left is addition, so add them up:

$108 + 10 + 20 = 118 + 20 = 138$ $108+10+20=118+20=138$

$138$ $138$

$8 + 100 + 10 + (4 + 4^{2})$ $8 + 100 + 10 + (4 + 4^2)$

$= 118 + (4 + 16)$ $=118 + (4 + 16)$

$= 118 + 20$ $=118 + 20$

$= 138$ $=138$

How do you evaluate 8+100+10+(4+42)8+ 100+ 10+ ( 4+ 4^ { 2} )?
