Answer 3

A) 513-4:4+11×8:

To solve this expression, we need to follow the order of operations, which is often remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break down the expression step by step:

1. 513 - 4: Here, we have subtraction. So, subtract 4 from 513, which gives us 509.

2. 509 ÷ 4: Next, we have division. So, divide 509 by 4, which gives us 127.25.

3. 127.25 + 11 × 8: Now, we have multiplication. Multiply 11 by 8, which gives us 88.

4. 127.25 + 88: Finally, we have addition. Add 127.25 and 88 together, which gives us 215.25.

Therefore, the result of the expression 513 - 4 ÷ 4 + 11 × 8 is 215.25.

B) 10 + (11 - 7) - 4:

Again, let's solve this expression step by step:

1. (11 - 7): Inside the parentheses, we have subtraction. So, subtract 7 from 11, which gives us 4.

2. 10 + 4 - 4: Now, we have addition and subtraction. Add 10 and 4, which gives us 14. Then subtract 4 from 14, which gives us 10.

Therefore, the result of the expression 10 + (11 - 7) - 4 is 10.
