Question

2)142+20*28-5445:11

Answer 1

142 + 20 × 28 - 5 445 ÷ 11 = 207.

1) 28 × 20 = 560;

2) 5 445 ÷ 11 = 495;

3) 560 + 142 = 702;

4) 702 - 495 = 207.

Answer 2

To solve this expression, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Using PEMDAS, we start with multiplication first, so we can simplify 20*28 to get 560.

Next, we can move on to the subtraction, so we can simplify 142-5445 to get -5303.

Finally, we can perform division to get -5303/11 which simplifies to -483.

Therefore, the solution to the expression 142+20*28-5445:11 is -483.
