Answer:

The simplification form of the number expression (-2 + 1)² + 5(12 : 3) - 9 is 12; the answer is 12.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

The number expression is:

= (-2 + 1)² + 5(12 : 3) - 9

The ratio can be described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

= (-1)² + 5(12/3) - 9

= 1 + 5(4) - 9

= 1 + 20 - 9

= 21 - 9

= 12

Thus, the simplification form of the number expression (-2 + 1)² + 5(12 : 3) - 9 is 12; the answer is 12.
