Digits and Place Values
This is an introductory tutorial outlining what digits and place values are. The associated video tutorial is to come.
What is a Digit?
A digit is any of the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
What is a Multiple Digit number?
A multiple digit number is any number that has more than one digit. That is, any whole number between 10 and 99 is a double digit number; similarly, any whole number between -10 and -99 is also a double digit number.
Knowing this, decide which of the below is a double digit, and which is a triple digit number. Hover your mouse over the image to reveal the answer.
What is a place value?
Every digit in a number is assigned a place value.
For example, in the number seventy-two, the digit 7 is assigned the tens' value; this tells you there are seven lots of 10s. The digit 2 is assigned the ones' value; this tells you that there are two lots of 1s.
The larger a number is (i.e. the more digits it has), the more place values it has. For example, the number 363,105 has six place values.
