123:6*7[ (654+2) * (12:3) ]

First do the brackets/parentheses

[ 654+2=656 & 12:3=4 ]

next you multiple the answer of two sums: 656x4 = 2624

Also don't forget to put in the parentheses because we need it. (2624)

Third, we going to divide 123:6=20.5

Fourth, we going to times 20.5 and 7 and that is equal to 143.5

Lastly, times 143.5 and 2624

The answer is 376,544

Step-by-step explanation:

123/6 x 7[ (654 + 2) x (12/3) ] ... do whats in parenthesis first

123/6 x 7[656 x 4] ... do whats in brackets

123/6 x 7 (2624) ... do multiplication/division from left to right, whichever comes first

20.5 x 18,368 =

376544 <===
