Explanation of the Expressions

Let's break down the expressions and explain what each of them means:

1. 27:9: This expression represents the division of 27 by 9. The colon symbol ":" is commonly used to denote division in mathematical expressions. So, 27:9 is equal to 3.

2. 18:9: Similarly, this expression represents the division of 18 by 9. Therefore, 18:9 is equal to 2.

3. 27+18: This expression represents the addition of 27 and 18. So, 27+18 equals 45.

4. (27+18):9: This expression combines addition and division. First, we add 27 and 18, which gives us 45. Then, we divide 45 by 9. Therefore, (27+18):9 is equal to 5.

To summarize: - 27:9 = 3 - 18:9 = 2 - 27+18 = 45 - (27+18):9 = 5

These are the values obtained by evaluating the given expressions.
