Introduction

Multiplication is a fundamental operation in mathematics that involves the repeated addition of a number. In this article, we will explore the concept of multiplication and how it can be used to solve equations. Specifically, we will examine the equation $-6 \times \square = -60$ and determine the integer that makes this equation true.

Understanding the Equation

The equation $-6 \times \square = -60$ involves the multiplication of the integer $-6$ by an unknown integer, denoted by the symbol $\square$ . The goal is to find the value of the unknown integer that makes the equation true.

To begin, let's consider the properties of multiplication. When we multiply two integers, the result is always an integer. In this case, the product of $-6$ and the unknown integer must be equal to $-60$ .

Properties of Multiplication

Multiplication is a commutative operation, meaning that the order of the factors does not change the result. In other words, $a \times b = b \times a$ . However, in this case, we are dealing with a negative integer, which affects the result of the multiplication.

When we multiply a negative integer by a positive integer, the result is always negative. Conversely, when we multiply a negative integer by a negative integer, the result is always positive.

Solving the Equation

To solve the equation $-6 \times \square = -60$ , we need to find the value of the unknown integer that makes the equation true. Let's start by isolating the unknown integer.

We can do this by dividing both sides of the equation by $-6$ . This gives us:

\square = \frac{-60}{-6}

Simplifying the Expression

Now, let's simplify the expression on the right-hand side of the equation.

\square = \frac{-60}{-6} = 10

Conclusion

Therefore, the integer that makes the equation $-6 \times \square = -60$ true is $\boxed{10}$ .

Why is this the Correct Answer?

The correct answer is 10 because when we multiply $-6$ by 10, the result is $-60$ . This is due to the properties of multiplication, specifically the commutative property and the effect of negative integers on the result.
