This process is called regrouping because you’re rearranging numbers into place value to carry out the process.
How do you use tens and units?
We count groups of ten and then count the single units. The digits written together in place value columns form our total number.
- The number 27 is made up of two. digits.
- The digit ‘7’ is in the units column and represents the value of ‘7’.
- The digit ‘2’ is in the tens column and represents the value of ’20’.
