7 + (2 + 6) 2 ÷ 4 ⋅ 1/2 Select one: a. 23 b. 18 c. 9 d. 8
Pemdas! You do 6+2 first and then multiply by 2. You get 16 and divide by 4, then divide by 1/2 and get 2. 2+7=9
These are one of those PEMDAS problems! This means go in order by parenthesis, exponents, multiplication, division, addition, and then subtraction.
So in parenthesis lets add 2 and 6
7 + (8)2 divided 4 times 1/2
Now multiply 8 and 2
7 + 16 divided 4 times 1/2
Now divided (because multiplication and division actually go together as like
one)
7 + 4 times 1/2
Now multiply 4 and 1/2
7 + 2
And now add
9
That's your answer ^
Hope that helps!
