Maths | Multiplication

Algorithm is a maths strategy that looks at the values of the digits in a number and uses that knowledge to solve an equation. Place Value solves equations by using the values of each digit. The Latis Method multiplies, divides, adds or subtracts each digit individually. A fact family is a group of maths facts that uses the same numbers. Multiplication is many groups of the same size.

Using algorithm, an equation such as 26 x 7 can be answered. Look at the values of each digit in the equation and split 26 into 20 and 6 to make the multiplication easier. Then multiply 6 by 7 to make 42, and 20 by 7 to make 140. Finally, 42 + 140 is 182, so 26 x 7 is equivalent to 182.

Take a complex equation like 26 x 17, which can still be solved using algorithm. Multiply 2 by 1 to make 2, and 6 multiplied by 1 to make 6.  Then, multiply 6 by 7 equals 14, and 6 multiplied by 7 equals 42. After that, the answers to each equation are added together. 2 + 6 + 14 + 42 = 442. So, 26 x 17 = 442.

The Latis method is multiplies each digit individually by another digit of a different number. The tens are the top left corner, and the ones are in the bottom left right. Multiply 2 by 1 to make 2 and 6 multiplied by 1 to make 6.  Then, multiply 6 by 7 to make 14, and 6 multiplied by 7 makes 42. After that, the totals are added together. 2 + 6 + 14 + 42 = 442. So 26 x 17 = 442.
