As you know, there are four basic mathematical operations. Addition, subtraction, multiplication, and division. These are needed even for daily life activities. There are even many jobs in our society that always make use of multiplication like banking, accounting, business, financing, etc. Even architects and engineers use multiplication in the calculation for various construction purposes.
Multiplication.
Why do we need multiplication tables?
Table of 255.
Faqs.
Multiplication means repeated addition. So a number is repeatedly added multiple times. The product of 2 and 3 means 2 is added 3 times. Instead of adding numerous times, you can just multiply those numbers. Here, the number that needs to be multiplied is 'multiplicand' and the number with which we multiply is called 'multiplier'. The result thus we obtain is the 'product'. The multiplicand and multiplier are interchangeable, and thus the answer would be the same irrespective of their arrangement. Some important points about multiplication and multiplication table are given below :
If any number is multiplied by zero, the answer will always be zero.
Any number multiplied by one is always the same number.
The order of numbers does not matter in multiplication.
If you want to multiply a number by 10, then just add a 'zero' at the end of the number. It is so easy!
Multiplication is a basic mathematical operation. There is a need to multiply two or more numbers, multiplication tables will be so helpful. It's like a crucial tool as we use it in our daily lives. It is so beneficial because it allows you to calculate large numbers within a short period. They are so convenient to employ as it shows the product of a number with consecutive natural numbers usually 1-10. This important mathematical idea assists in the quick computation of numerals and also serves as an effective way to remember.

When we multiply 255 and 12,
255\times12=3060
255×12=3060.
The answer is 3060.
Number of oranges Justin will eat per day = 4
Number of days he will eat = 255
So the total number of oranges = 255\times4=1020
255×4=1020 oranges.
Number of lessons Melissa has to revise = 255
Time given for each lesson = 3 hours
So total time she would take =
255\times3=765
225×3=765 hours.
Now, one day has 24 hours. So if she has to study
675 hours it would take \frac{765}{24}=32
765÷24=32 complete days.
