Problem 43 - Beginning and Intermediate Algebra

Question

Find each sum or product. $$ 97+13+3+37 $$

Step-by-Step Solution

Answer

150

Step 1: Add 97 and 13

First, add the numbers 97 and 13 together. Hence, 97 + 13 equals 110.

Step 2: Add 110 and 3

Next, take the result from Step 1, which is 110, and add 3 to it. So, 110 + 3 equals 113.

Step 3: Add 113 and 37

Finally, take the result from Step 2, which is 113, and add 37 to it. Therefore, 113 + 37 equals 150.

Key Concepts

Addition

Addition is one of the basic arithmetic operations where two or more numbers, known as addends, are added together to form a sum.
To add successfully, line up numbers by their place values (units, tens, hundreds, etc.).
The process is straightforward:

• Start from the rightmost digit (units place) and move towards the left.
• Carry over if the sum exceeds 9.

Addition is commutative, meaning you can add numbers in any order and still get the same result.

Step-by-step solution

Breaking down a problem into smaller steps can make it easier to understand and solve.
For our exercise, we used a step-by-step approach:

• Step 1: Add the first two numbers, 97 and 13. This gives us 110.
• Step 2: Next, add 3 to the result of Step 1, resulting in 113.
• Step 3: Finally, add 37 to the new sum, resulting in 150.

This organized method helps keep track of each part of the problem and ensures accuracy.

Whole numbers

Whole numbers are numbers without fractions or decimals. They include all positive integers and zero (0, 1, 2, 3,...).
Whole numbers are essential in arithmetic operations like addition because they are simple and straightforward to work with.
In our exercise, we added whole numbers: 97, 13, 3, and 37.
These numbers are easy to manage, and their sums are also whole numbers.
Remember, whole numbers are always non-negative and can be visualized on a number line.
