Multiplication using Signs and Parentheses<\/h3>\n
The multiplication using signs and parentheses is the same. The sign of a number shows the impact on the product. The multiplication of two positive numbers is a positive number. The multiplication of a positive and a negative number is a negative number. The multiplication of two negative numbers is a positive number.<\/p>\n
Examples:<\/strong>
\n4 . 2 = 4 times 2 = 8
\n5 . 6 = 5 times 6 = 30
\n8(6) = 8 times 6 = 48
\n-7(4) = -7 times 4 = -28
\n4 . -5 = -20
\n-3(-6) = 3 times 6 = 18<\/p>\nMultiply a Number with a Larger Number<\/h3>\n

- Find two numbers in two columns.<\/li>\n
- Multiply the unit digit of the second number by the first number.<\/li>\n
- Again, multiply the ten’s digit of the second number by the first number.<\/li>\n
- Repeat the process until you left nothing on the left side of the second number.<\/li>\n
- Add the products to get the final product.<\/li>\n<\/ul>\n
How to Multiply a Number Quickly?<\/h3>\n
We use this process when any of the numbers are in the form of 100 or 200 or 500 or 90 or so on.<\/p>\n

- Let us take two numbers.<\/li>\n
- To do mental calculations, remove zeros in both numbers.<\/li>\n
- Multiply the remaining numbers.<\/li>\n
- Add the number of zeros available in both numbers on the right side of the product.<\/li>\n
- The final obtained is the product of numbers.<\/li>\n<\/ul>\n
Questions and Answers on Multiply a Number<\/h3>\n
Question 1:<\/strong>
\nHow to multiply a number by 10, 100, 1000?
\n(a) 125 x 10
\n(b) 874 x 100
\n(c) 24 x 1000
\nSolution:<\/strong>
\n(a) Given that,
\n125 x 10 = 125 x 1 0
\n= 1250
\n(b) Given that,
\n874 x 100 = 874
\n(c) Given that,
\n24 x 1000 = 24 x 1 000
\n= 24000
\nMultiply by 10 means digits shift one place to the left.
\nMultiply by 100 means digits shift two places to the left.
\nMultiply by 1000 means digits shift three places to the left.<\/p>\nQuestion 2:<\/strong>
\nHow to multiply a number by 200, 300, 400?
\n(a) 245 x 200
\n(b) 456 x 300
\n(c) 182 x 400
\nSolution:<\/strong>
\n(a) Given that,
\n245 x 200 = 2 4 5 x 2 x 100
\nFirst, we multiply non zero digits
\n245 x 2 = 490
\nThen we count the number of zeros in both the factors and place them at the end.
\n245 x 200 = 49000
\n(b) Given that,
\n456 x 300 = 456 x 3 x 100
\nFirst, we multiply non zero digits
\n456 x 3 = 1368
\nThen we count the number of zeros in both the factors and place them at the end.
\n456 x 300 = 136800
\n(c) Given that,
\n182 x 400 = 182 x 4 x 100
\nFirst, we multiply non zero digits
\n182 x 4 = 728
\nThen we count the number of zeros in both the factors and place them at the end.
\n182 x 400 = 72800<\/p>\nQuestion 3:<\/strong>
\nCompute 56 x 43
\nSolution:<\/strong>
\nGiven that,
\n56 x 43
\n![\"Multiply](\"https:\/\/ccssanswers.com\/wp-content\/uploads\/2021\/06\/multiply-a-number-1.png\")
\n56 x 43 = 2408
\nHere, 56 and 43 are factors, 2408 is the product.<\/p>\n","protected":false},"excerpt":{"rendered":"Multiplication is one of the arithmetic operations which means repeated addition.
