What is multiplication algorithm?
A multiplication algorithm is an algorithm (or method) to multiply two numbers. Depending on the size of the numbers, different algorithms are used. Efficient multiplication algorithms have existed since the advent of the decimal system.
What are the 2 stages of the multiplication algorithm teaching sequence?
Teaching algorithms for multiplication
- Stage 1: Develop meaning(s) for multiplication.
- Stage 2: Multiplication by a single digit.
- Stage 3: Multiplication by ten.
- Stage 4: Multiplication by a multiple of ten.
- Stage 5: Multiplication by numbers with two or more digits.
What is algorithm method?
An algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conducting a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.

Which is an example of a commutative property of multiplication?
Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30.
