Question

0*(100-81)+642*1=? 816+942:4-386=?

Answer 1

Решение:

0*(100 - 81) + 642 * 1 = 642

1. 0 * (100 - 81) = 0
2. 642 * 1 = 642
3. 0 + 642 = 0

816 + 942 : 4 - 386 = 665.5

1. 942 : 4 = 235.5
2. 816 + 235.5 = 1 051.5
3. 1 051.5 - 386 = 665.5

Answer 2

Let's solve each expression step by step:

1. 0 * (100 - 81) + 642 * 1

First, calculate the expression inside the parentheses: 100 - 81 = 19 Next, multiply the result by 0: 0 * 19 = 0 Finally, add the result to 642 multiplied by 1: 0 + 642 = 642

So, the answer is 642.

2. 816 + 942 : 4 - 386

The expression involves division, so let's start with that:

942 : 4 = 235.5

Next, add 816 to the division result:

816 + 235.5 = 1051.5

Finally, subtract 386 from the sum:

1051.5 - 386 = 665.5

So, the answer is 665.5.
