TermDefinitionExample Division FactA basic division problem and its answer, often derived from multiplication facts (e.g., 12 ÷ 3 = 4 because 3 × 4 = 12).20 ÷ 5 = 4 is a division fact. DividendThe number being divided in a division problem.In 30 ÷ 5 = 6, the dividend is 30. DivisorThe number by which another number is divided.In 30 ÷ 5 = 6, the divisor is 5. QuotientThe result obtained when one number is divided by another.In 30 ÷ 5 = 6, the quotient is 6. DivisibilityThe ability of one number to be divided by another number without leaving a remainder.24 is divisible by 4 because 24 ÷ 4 = 6 with no remainder. Mental MathPerforming mathematical calculations in your head without the aid of a calculator or written work.Quickly calculating 40 ÷ 5 = 8 without writing it down.

Divisibility Rule for 2 A number is divisible by 2 if its last digit is an even number (0, 2, 4, 6, or 8). This rule helps quickly identify if a number can be divided into two equal groups without any leftover. For example, 78 is divisible by 2 because its last digit is 8. Divisibility Rule for 3 A number is divisible by 3 if the sum of its digits is divisible by 3. This rule is useful for larger numbers. Add all the digits of the number; if that sum is a multiple of 3, then the original number is also a multiple of 3. For example, for 123, 1 + 2 + 3 = 6, and 6 is divisible by 3, so 123 is divisible by 3. Divisibility Rule for 5 A number is divisible by 5 if its last digit is 0 or 5. This rule is straightforward and helps identify numbers that can be grouped into fiv...
