# Adding whole numbers by their place values

Lindsay adds numbers like 19 thousands + 7 tens by thinking about their place values.

## Want to join the conversation?

• would 3 hundreds + 17 tens equal 470?
• yes, u r correct
• why would the answer be 72,000
• because 22,000 is equal to 20,000+2,000 so 50,000+22,000=72,000
• how do you add 10000,000 +1096548647346
• You break them into small parts and the answer is 1.0965487e+12 in numbers.
• is 1000 x 5000 =1000000000
• Why do some people pronounce numbers the wrong way on purpose? An example: 19 hundred
• 19 hundred is a short way of saying one thousand 9 hundred.
people say it because its true. 19 * 100 = 1900
• When you use the blocks do you count them based on the performance task or by how much it is worth?
• What is the difference between a place value and a value?

• A value can be any numerical quantity. For example, 14 is a value, 1590 is a value, 3 is a value, 999 is a value. They all represent amounts.

Place value relates to the position of a number in a value and depending on the position of a number in a value, the value it represents would be different. For example, in the number 1590, the 1 is first, the 5 is second, the 9 is third, and the 0 is fourth. So because of the positions, the place of the value 1 would represent how many thousands, the place of the value 5 would represent how many hundreds, the place of the value 9 would represent how many tens, and the place of the value 0 would represent how many ones.

If you had instead 5019, you would have all the same values like in the previous number (1, 5, 9, 0) but this value 5019 represents a different amount because all the values 1, 5, 9, and 0 are in different positions so they have different place values and therefore represent a different value. You would then have 5 thousands, 0 hundreds, 1 ten, and 9 ones.
• so that means 19000+70=19070 right
