Question

What is the value of the expression [36-9+(8x6)-21]divided by 3

Answer 1

18

Explanation:

using Pemdas

you would do the parentheses first

in the parentheses theres parentheses so 8*6 is 48

then do the rest of the parentheses so 36-9+48-21 which equals 54

then lastly divide by 3

which equals 18

Answer 2

12-3+(2.7x2)-7

Explanation:

you would have to divide each number in the equation by 3 which would look like this:

36 / 3 = 12

-9 / 3 = -3

8 / 3 = 2.6666 repeating, which would be rounded up to 2.7

6 / 3 = 2

-21 / 3 = -7

i hope this helps :)
