Tens and Ones


What is tens in math?

In math, the second digit (from right to left) of a number is considered as the tens placed digit. And this digit place value = face value of the digit X 10.

Example:

5 is placed in tens of 56.

So, its place value = 5 X 10 = 50.

What is ones in math?

In math, the first digit (from right to left) of a number is considered as the ones placed digit. And this digit place value = face value of the digit X 1.

Example:

6 is placed in ones of 56.

So, its place value = 6 X 1 = 6.
