Question

100+(4-4)*8-9*9= 0:42+48:6+(6*4+21):5=

Answer 1

Первый пример
1) 4-4=0
2) 0*8=0
3) 9*9=81
4) 0-81=-81
5) 100-81=9
второй пример
1) 6*4=24
2) 24+21=45
3) 45:5=9
4) 0:42=0
5) 48:6=8
6) 9+0=9
7) 9+9=18

Answer 2

Let's break down each equation step by step:

1. 100 + (4-4) * 8 - 9 * 9 =

   First, we solve the expression within the parentheses, which is 4-4, and the result is 0.

   Then, we perform the multiplication between 0 and 8, and the result is 0.

   Next, we multiply 9 by 9, and the result is 81.

   Finally, we subtract 0 from 100 and then subtract 81 from the result:

   100 - 0 - 81 = 19

   Therefore, 100 + (4-4) * 8 - 9 * 9 = 19.

2. 42 + 48 : 6 + (6 * 4 + 21) : 5 =

   First, we perform the division between 48 and 6, and the result is 8.

   Next, we solve the expression within the parentheses, which is 6 * 4 + 21, and the result is 45.

   Then, we perform the division between 45 and 5, and the result is 9.

   Finally, we add 42, 8, and 9:

   42 + 8 + 9 = 59

   Therefore, 42 + 48 : 6 + (6 * 4 + 21) : 5 = 59.
