Solved Problems Involving Multiplication of Whole NumbersĬase(i): Multiplying a multi-digit number by a one-digit number is Step 3: Add the partial products to obtain the total product in multiplication. The tens digit is used as a factor, second partial product is written right below the first partial product so that its rightmost digit appears in the tens column. Step 2: Now, multiply the multiplicand by the tens digit of the multiplier is called the second partial product. Step 1: Multiply the multiplicand by the one digit of the multiplier is called the first partial product. In multiplication, when the multiplier is composed of two or more digits.
#Whole numbers how to
If a,b and c are three whole numbers then, a * (b – c) = (a * b) – (a * c).ġ0 * (6 – 3) = (10 * 6) – (10 * 3) = 30 What are the Steps in Multiplying Whole Numbers? | How to Multiply Whole Numbers? This property states that the multiplication of whole numbers is distributed all over the difference of the whole numbers. Property 7: Distributive Property of Multiplication over Subtraction If a,b and c are three whole numbers then, a * (b + c) = (a * b) + ( a * c). This property states that multiplication of whole number is distributed all over sum of the whole numbers. Property 6 : Distributive Property of Multiplication over Addition Let w be the whole number then, w * 0 = 0. This property states that when we multiply any whole number with 0, the product will be 0. Property 5: Multiplicative property of Zero This property states that when we multiply any whole number with 1, the product will be the number itself. Let us consider a,b and c are three whole numbers, then a * (b * c) =( a * b) * c. Let us consider a and b are two whole numbers then a * b = b * a.Īssociative property states that when we multiply three or more whole numbers, the value of the product does not change. Let us consider a and b are two whole numbers and they multiply to obtain the result c, which is also a whole number i.e a * b = c.Įxample : 4 * 5 = 20, therefore 20 is a whole number.Ĭommutative property states that the order of multiplication does not change the value of the product. Properties of Multiplying Whole NumbersĬlosure property states that multiplication of any two whole numbers will result in a whole number. If you multiply a number a by another number b, this is same as adding the number an over and over again b times.Įxample : 5 x 7 = 5 + 5 + 5 + 5 + 5 + 5 + 5 = 35įive multiplied by seven equals thirty-five, where 5 and 7 are multiplicand and multiplier. “, which is used to multiply and the equal symbol notated as “ = “ gives the product. Multiplication is written by using a mathematical operator cross “ x “ or asterisk “ * “ or dot “. The result of the multiplication is called a product. In Multiplication, the repeated number(the number being added) is called multiplicand, and the number that records the number of times the multiplicand is used known as the multiplier.
Multiplication of two numbers is nothing but equivalent to adding as many copies of one of them. Multiplication is defined as the basic idea of repeated addition.
