A Base 10 Number system means:

Accepted Answer

Regrouping once you have a bundle of 10

Accepted Answer

With every shift in place value, the value of the digits become 10 times greater or 10 times smaller moving left or right

Accepted Answer

If it is necessary to "borrow" (regroup from the larger place value to the left over to the smaller place value next door), it is always a bundle of 10 that is added to the smaller place value.

Accepted Answer

Only the numerals 0-9 are used to build our numbers

Accepted Answer

With every shift to the right in a number, the value of the digits are $$\frac{1}{10}$$ the value of the digits to the left.
