98.4 Plus 1.78

98.4 plus 1.78 is a simple arithmetic problem that can be solved using basic addition. However, when dealing with decimal numbers, it's essential to understand the concept of place value and how to align the numbers correctly to ensure accurate results.

Understanding Decimal Numbers

Decimal numbers are based on the concept of place value, where each digit has a specific value based on its position. In the number 98.4, the 8 is in the tens place, the 9 is in the ones place, and the 4 is in the hundredths place. To add 1.78 to 98.4, we need to align the numbers correctly and perform the addition step by step.

Step-by-Step Addition

Here's a step-by-step guide to adding 98.4 and 1.78:

• First, we need to align the decimal points of the two numbers. We can do this by placing a decimal point after the 8 in 98.4.
• Next, we add the numbers in the hundredths place. Since 4 + 8 = 12, we write down 2 and carry over 1 to the tenths place.
• Now, we add the numbers in the tenths place, including the carried over 1. We get 9 + 1 + 7 = 17, so we write down 7 and carry over 1 to the ones place.
• Finally, we add the numbers in the ones place, including the carried over 1. We get 8 + 1 + 0 = 9.
