Question

(2 + 8) : 5 + 3 x 4 – (1 + 5) : 2 =

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given expression

`(2+8):5+3*4-(1+5)\colon2`

STEP 2: Simplify the expression

`\begin{gathered} \mathrm{Follow\:the\:PEMDAS\:order\:of\:operations} \\ (2+8)=10 \\ =10/ \:5+3\cdot \:4-\left(1+5\right)/ \:2 \end{gathered}`

Calculate within parentheses

`\begin{gathered} (1+5)=6 \\ =10/ \:5+3\cdot \:4-6/ \:2 \end{gathered}`

Multiply and divide from left to right

`=2+3\cdot \:4-6/ \:2`
`\begin{gathered} 3\cdot4=12 \\ 6/2=3 \end{gathered}`

So we have;

`\begin{gathered} =2+12-3 \\ =14-3=11 \end{gathered}`

Hence, the answer is 11
