Question

I need the result step by step: 18+6[26-7(1+2])

Answer 1

Answer:

$\Huge \boxed{48}$

Step-by-step explanation:

$\bigstar\Large\boxed{\textnormal{Order of operations}}\bigstar$

To use order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) the numbers from left to right. Please Excuse My Dear Aunt Sally!

First, solve parenthesis.

$\displaystyle [26-7(1+2)])$

$\displaystyle (1+2)=3$

$\displaystyle 26-7*3$

$\displaystyle 7*3=21$

$\displaystyle 26-21=5$

$\displaystyle 18+6*5$

Next, multiply numbers from left to right.

$\displaystyle 6*5=30$

Then, add numbers from left to right.

$\displaystyle 18+30=\boxed{48}$

$\bigstar\Large\boxed{\textnormal{Therefore, the correct answer is \boxed{48}}}.\bigstar$

Answer 2

So first you start within the parentheses

1+2= 3

18+6(26-7 3)

-7*3=-21

18+6(-21+26)

-21+26=5

18+6*5

6*5=30

18+30= 48

Therefore 48 would be the answer...remember to follow (PEMDAS)!
