Base 10 refers to the numbering system in common use. Take a number like 475, base ten refers to the position, the 5 is in the one's place, the 7 is in the ten's place and the 4 is in the hundred's place. Each number is 10 times the value to the right of it, hence the term base ten. The numbers continue indefinitely in this pattern: 100000,10000,1000,100,10,1 0.1, 0.01, 0.001, 0.0001, 0.00001
Base 10 blocks are often used in early education in math to help students grasp number. Base 10 blocks have a cube to represent one, ten cube strip to represent ten and a 100 cube block to represent 100. Base 10 also represents the powers of base ten.
