Answer 1

1)35:5+18-100
2)100-35+18:5
3)18+5:35-100

Answer 2

((100-35)/5)+18
(100-(35/5)+18
100-((35/5)+18)

Answer 3

Calculations with Parentheses

To solve the given expressions, we need to follow the correct order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

1. 1 + 2 + 3 + 100 - 35 : 5 + 18 = - First, we need to perform the division inside the parentheses: 35 ÷ 5 = 7 - Then, we calculate the sum: 1 + 2 + 3 + 100 - 7 + 18 = 117

2. 2 + 1 + 3 + 100 - 35 : 5 + 18 = - Again, we start by performing the division inside the parentheses: 35 ÷ 5 = 7 - Then, we calculate the sum: 2 + 1 + 3 + 100 - 7 + 18 = 117

3. 3 + 1 + 2 + 100 - 35 : 5 + 18 = - Once more, we begin by performing the division inside the parentheses: 35 ÷ 5 = 7 - Then, we calculate the sum: 3 + 1 + 2 + 100 - 7 + 18 = 117

So, the result for all three expressions is 117.

This means that regardless of the order in which the numbers are added, the result remains the same due to the associative property of addition.

I hope this helps clarify the calculations! If you have any more questions or need further assistance, feel free to ask!
