Grade 1 Math Tens and Ones
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.
