Problem 62 - Fundamentals of Mathematics

Question

Subtract 35 from 86 .

Step-by-Step Solution

Answer

The result is 51.

Step 1: Identify the Operation

We need to subtract 35 from 86. This means that the operation required is subtraction.

Step 2: Write Down the Numbers

The larger number is 86, and the number to be subtracted from it is 35. So, we write the subtraction as:\[86 - 35\]

Step 3: Perform the Subtraction

Subtract 35 from 86.1. Subtract the units: 6 - 5 = 1.2. Subtract the tens: 8 - 3 = 5.So, the result of the subtraction is \(51\).

Key Concepts

Step-by-step solution

A step-by-step solution is like a guided path that takes you through the subtraction process. It breaks down each part of the problem, making it easier to handle one piece at a time. This approach is especially useful in understanding how subtraction works.

• Identify the Operation: First, we need to understand what the math problem is asking us to do. In this case, it is asking us to subtract.
• Write Down the Numbers: Clearly writing the numbers involved helps in visualizing the subtraction. We write the larger number first, and the number we want to subtract below it, aligned at the right.
• Perform the Subtraction: Finally, we calculate the difference starting from the units place and moving towards the left to the tens place.

Step-by-step solutions ensure that we do not miss any critical part of the process. This organized method makes solving subtraction easier and more accurate.

Arithmetic operation

Arithmetic operations are the building blocks of mathematics. They include addition, subtraction, multiplication, and division, and help us to solve everyday math problems. Each operation has its own unique purpose and application.

• Addition: Combines numbers to find the total or sum.
• Subtraction: Finds the difference between numbers or how much one number surpasses another.
• Multiplication: Involves repeated addition of the same number.
• Division: Splits a number into equal parts.

In the problem we discussed, subtraction is our focus. It's a fundamental arithmetic operation used to find what remains when one number is taken away from another. Understanding arithmetic operations helps us tackle more complex mathematical concepts confidently.

Subtracting whole numbers

Subtracting whole numbers involves removing a certain value from a greater number. This process helps to determine the remaining amount or difference. It's crucial to subtract numbers correctly by aligning them properly and starting from the rightmost digit.

Here's a quick way to remember the process of subtracting:

• Align the Numbers: Ensure that each digit is in the right column – units under units, tens under tens.
• Start from the Units: Begin subtracting from the rightmost column. If the top digit is smaller, consider borrowing from the next left column.
• Move to the Tens: After the rightmost column, proceed left to the tens column and perform the subtraction.

Being careful with alignment and starting from the units digit ensures accuracy in subtraction. Practicing this method can help improve your skills in subtracting whole numbers effectively.
