Why is the number system called 'base 10'?

• Because it uses 10 digits to represent numbers

• Because it uses 10 different operations

• Because it has 10 different colors

• Because it is based on 10 different shapes

What happens when you multiply a number by 10 in the base 10 system?

• The number shifts one place to the left

• The number remains the same
