Answer 3

Let's solve these expressions step by step:

1. (24 + 49 - 55) * (20 * 4 - 15 * 5) First, calculate the values inside each set of parentheses:

   • Inside the first set of parentheses: 24 + 49 - 55 = 18
   • Inside the second set of parentheses: 20 * 4 - 15 * 5 = 80 - 75 = 5

   Now, multiply the results of the two sets of parentheses: 18 * 5 = 90

2. (57 + 18 : 6) : 10 + 60 : 2 - 15 : 5 Let's break down the expression step by step:

   • Inside the first set of parentheses: 57 + 18 ÷ 6 = 57 + 3 = 60
   • Divide the result by 10: 60 ÷ 10 = 6
   • Divide 60 by 2: 60 ÷ 2 = 30
   • Divide 15 by 5: 15 ÷ 5 = 3

   Now, substitute the values back into the expression: 6 + 30 - 3 = 33

So, the solutions are:

1. (24 + 49 - 55) * (20 * 4 - 15 * 5) = 90
2. (57 + 18 : 6) : 10 + 60 : 2 - 15 : 5 = 33
