Introduction

As a professional teacher, one of the most common questions I get from students is how to solve mathematical problems. One such problem that often confuses students is "7 8 x 1 2". In this article, we will explore what this problem means and how to solve it step by step.

What Does "7 8 x 1 2" Mean?

The first step in solving any mathematical problem is to understand what it means. In the case of "7 8 x 1 2", the problem involves multiplication and two-digit numbers. The x symbol is a shorthand for multiplication, which means we need to multiply the two numbers on either side of it.

The Order of Operations

Before we start multiplying, we need to follow the order of operations. The order of operations is a set of rules that tells us which mathematical operation to perform first. The acronym PEMDAS can help us remember the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). In "7 8 x 1 2", we don't have any parentheses or exponents, so we can move straight to multiplication.

Multiplying Two-Digit Numbers

To multiply two-digit numbers, we use a method called long multiplication. We start by multiplying the ones place of the second number by the first number, then we move on to the tens place. We add the two products together to get the final answer. For example, to multiply 78 by 12, we would do the following: ``` 78 x 12 ---- 156 (8 x 2) 780 (8 x 1, with a zero placeholder) ---- 936 (the final answer) ```

Solution

Now that we know how to multiply two-digit numbers, we can apply this method to "7 8 x 1 2". Using long multiplication, we get: ``` 78 x 12 ---- 156 (8 x 2) 780 (8 x 1, with a zero placeholder) ---- 936 (the final answer) ``` Therefore, the solution to "7 8 x 1 2" is 936.

Conclusion

In conclusion, "7 8 x 1 2" is a multiplication problem that involves two-digit numbers. To solve it, we need to follow the order of operations and use long multiplication to multiply the two numbers together. By breaking down the problem into smaller steps, we can make it easier to understand and solve.
