To solve this problem, you need to do it in this order: PEMDAS
(Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
2 × 4 ÷ 6(8 × 3) - 6 = Y First simplify inside the ( ), and multiply 8 by 3
2 × 4 ÷ 6(24) - 6 = Y Now multiply 6 and 24
2 × 4 ÷ 144 - 6 = Y Multiply 2 and 4
8 ÷ 144 - 6 = Y Divide 8 and 144
18 - 6 = Y Subtract 18 and 6
12 = Y
The answer is 4.608*10^-2
