# Number & Operations in Base Ten (NBT)

In the Number & Operations in Base Ten domain, K-5 students should develop an understanding of the base-ten system. The base-ten system uses 10 digits, 0-9, to represent every number. The number's position determines its place value, as in 326 is 3 hundreds, 2 tens and 6 ones. Understanding the base-ten system helps students work with decimals (small numbers) and exponents (very large numbers).
