Chapter 1: Problem 49

Perform the operations. Subtract 10 from the sum of 8 and ?5.

Short Answer

Expert verified

The result of the operation is 3.

Step by step solution

Calculate the Sum

First, we need to determine the sum of 8 and 5 (since the typical question should not have a question mark before a number for arithmetic operations). Hence, calculate \[8 + 5 = 13\]

Subtract the Given Number

Now, subtract 10 from the sum we calculated in Step 1. The expression now is \[13 - 10 = 3\]

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Addition

When we talk about addition in basic arithmetic, we are referring to the process of combining two or more numbers to get a total or sum. This operation is one of the fundamental building blocks of mathematics and is something we often use in everyday life. In the exercise you saw, we needed to add the numbers 8 and 5.

Here's how addition works:

Identify the numbers you want to add together鈥攊n this case, 8 and 5.
Align them properly if you are adding them vertically.
Add the numbers starting from the rightmost side (though in this case, both are single digits).
The result of the addition was 13, indicating the total when 8 and 5 are combined.

Addition is a straightforward process, but it's important to ensure that each number is correctly accounted for, especially when dealing with larger numbers. Being proficient in addition can help in various aspects of life, like making purchases or keeping track of scores during a game.

Subtraction

Subtraction is another key arithmetic operation that is essential for solving many types of problems. It involves taking one number away from another and is often used to determine the difference between two numbers. In our example, we needed to subtract 10 from the sum of 13.

Here's a quick guide to subtraction:

Find the numbers you will be using鈥攈ere, 13 is the minuend (the number you are subtracting from) and 10 is the subtrahend (the number to be subtracted).
If arranging them vertically, ensure they are aligned correctly, with each digit in the correct column.
Subtract starting from the rightmost digit; in this case, 13 minus 10 equals 3.

Subtraction helps in a variety of contexts, like determining how much money is left after a purchase, or how much more time is needed to complete a task. Mastery of subtraction can also aid in understanding more complex mathematical concepts like equations and algebraic expressions.

Problem Solving

Problem solving in mathematics often involves more than just applying one operation. It requires identifying which operations are needed, in what order they should be performed, and sometimes, re-evaluating what you know to ensure accuracy.

Here鈥檚 how to approach problem solving as applied in the exercise:

Understand the problem: First, identify what is being asked. In this case, you are asked to subtract 10 from the sum of 8 and 5.
Plan your approach: Determine the necessary steps. For this exercise, the first step involved calculating the sum of 8 and 5, followed by subtracting 10.
Execute the plan: Carry out the operations in the correct order鈥攁dd first, then subtract.
Verify your solution: It鈥檚 always wise to check that your solution makes sense, ensuring all calculations have been done correctly.

Being systematic in your approach to problem solving can make seemingly complex tasks more manageable. Whether in academic tasks or daily activities, honing these skills will help you tackle a wide range of challenges efficiently.
