Introduction

Mathematical expressions are a fundamental part of mathematics, and solving them is an essential skill for anyone who wants to excel in mathematics. In this article, we will focus on solving a specific mathematical expression: (88−9×4)+77=(88 - 9 \times 4) + 77 =. We will break down the expression into smaller parts, apply the order of operations, and finally arrive at the solution.

Understanding the Order of Operations

Before we dive into solving the expression, it's essential to understand the order of operations. The order of operations is a set of rules that tells us which operations to perform first when we have multiple operations in an expression. The order of operations is often remembered using the acronym PEMDAS, which stands for:

  1. Parentheses: Evaluate expressions inside parentheses first.
  2. Exponents: Evaluate any exponential expressions next.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Breaking Down the Expression

Now that we understand the order of operations, let's break down the expression (88−9×4)+77=(88 - 9 \times 4) + 77 =.

The expression contains three main parts:

  1. 88−9×488 - 9 \times 4
  2. +77+ 77

We will start by evaluating the first part of the expression, which is 88−9×488 - 9 \times 4.

Evaluating the First Part of the Expression

To evaluate the first part of the expression, we need to follow the order of operations. We will start by evaluating the multiplication operation, which is 9×49 \times 4.

9×4=369 \times 4 = 36

Now that we have evaluated the multiplication operation, we can substitute the result back into the expression.

88−3688 - 36

Next, we will evaluate the subtraction operation.

88−36=5288 - 36 = 52

So, the first part of the expression is equal to 5252.

Evaluating the Second Part of the Expression

Now that we have evaluated the first part of the expression, we can move on to the second part, which is +77+ 77.

To evaluate the second part of the expression, we need to add 7777 to the result of the first part.

52+77=12952 + 77 = 129

So, the final result of the expression is 129129.

Conclusion

In this article, we solved a mathematical expression using the order of operations. We broke down the expression into smaller parts, evaluated each part, and finally arrived at the solution. The expression was (88−9×4)+77=(88 - 9 \times 4) + 77 =, and the final result was 129129. We hope that this article has provided you with a clear understanding of how to solve mathematical expressions using the order of operations.

Q: Why is it important to follow the order of operations?

A: Following the order of operations is essential to ensure that mathematical expressions are evaluated correctly. If we don't follow the order of operations, we may get incorrect results.

Q: How do I use parentheses to group expressions?

A: To use parentheses to group expressions, simply place the expressions you want to group inside the parentheses. For example, if we have the expression 2×(3+4)2 \times (3 + 4), we would group the expressions inside the parentheses first.

Q: What is the difference between multiplication and division?

A: Multiplication and division are both operations that involve numbers, but they have different rules. Multiplication involves multiplying two or more numbers together, while division involves dividing one number by another.

Q: How do I evaluate exponential expressions?

A: To evaluate exponential expressions, we need to raise the base number to the power of the exponent. For example, if we have the expression 232^3, we would raise 2 to the power of 3, which equals 8.

Q: What is the difference between addition and subtraction?

A: Addition and subtraction are both operations that involve numbers, but they have different rules. Addition involves combining two or more numbers together, while subtraction involves finding the difference between two numbers.

Q: How do I evaluate addition and subtraction operations?
