What is seven hundreds plus thirteen tens?a)713b)7130c)731d)830Correct...
To solve this problem, we need to understand the place value system and addition.
Place value system:
- The place value of a digit determines its value in a number.
- The place value increases from right to left, with each place representing a power of 10.
- The first place to the left of the decimal point is the ones place, followed by the tens place, hundreds place, and so on.
Addition:
- Addition is the process of combining two or more numbers to find their total sum.
- When adding numbers, we need to align them based on their place value before adding the corresponding digits.
Now, let's break down the given problem step by step:
Step 1: Understanding the numbers
- "Seven hundreds" means 700. This number has a digit in the hundreds place and no digits in the tens or ones places.
- "Thirteen tens" means 130. This number has digits in the tens place and no digits in the hundreds or ones places.
Step 2: Aligning the numbers
- We need to align the numbers based on their place value before adding them. In this case, since the numbers have digits in different places, we can align them as follows:
700
+ 130
Step 3: Adding the corresponding digits
- Start by adding the digits in the ones place. Since there are no digits in the ones place for both numbers, we move on to the tens place.
- Add the digits in the tens place: 0 + 3 = 3.
- Finally, add the digits in the hundreds place: 7 + 1 = 8.
Step 4: Writing the final answer
- The sum of 700 and 130 is 830.
Therefore, the correct answer is option D) 830.
