How to Memorize the Table of 79 Quickly
FAQs on Table of 79: Learn and Download Multiplication Table of 79
1. What is the multiplication table of 79 from 1 to 10?
The multiplication table of 79 lists the results of multiplying 79 by whole numbers. The first ten multiples are essential for learning and quick calculations:
79 x 1 = 79
79 x 2 = 158
79 x 3 = 237
79 x 4 = 316
79 x 5 = 395
79 x 6 = 474
79 x 7 = 553
79 x 8 = 632
79 x 9 = 711
79 x 10 = 790
2. Is there a simple trick to memorise the 79 times table?
Yes, a very effective trick is to use the table of 80, which is easier to calculate. Since 79 = 80 - 1, you can find any multiple of 79 by first multiplying by 80 and then subtracting the multiplier. For example, to find 79 x 6:
First, calculate 80 x 6 = 480.
Then, subtract the multiplier (6) from the result: 480 - 6 = 474.
So, 79 x 6 = 474. This method simplifies mental calculations significantly.
3. How do you solve a problem like 79 x 14 using the table?
You can solve this by breaking down 14 into smaller, manageable parts using the distributive property of multiplication. A common way is to split 14 into (10 + 4).
First, find 79 x 10, which is 790.
Next, find 79 x 4, which is 316.
Finally, add the two results together: 790 + 316 = 1106.
This shows how knowing the basic table up to 10 helps in solving larger multiplication problems.
4. Why is 79 considered a prime number and what does that mean for its multiplication table?
A prime number is a whole number greater than 1 that has only two factors: 1 and itself. The number 79 is prime because the only numbers that can multiply to get exactly 79 are 1 × 79. This means that in its multiplication table, every result (like 158, 237, etc.) will have 79 as one of its prime factors, but you cannot arrive at 79 by multiplying any other two whole numbers together.
5. What is an example of using the table of 79 in a word problem?
Here is a practical example: If a special edition book costs ₹79 and a school library decides to buy one for each of its 8 classes, what would be the total cost? To solve this, you need to calculate 79 x 8. By referring to the multiplication table of 79, we find that 79 x 8 = 632. Therefore, the total cost for the books would be ₹632.
6. What is the pattern in the last digit of the multiples in the 79 times table?
The last digits of the multiples in the 79 times table follow a repeating pattern. If you look at the sequence from 79 x 1 to 79 x 10, the last digits are: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0. This is a simple descending sequence. This pattern repeats for the next set of ten multiples (from 79 x 11 to 79 x 20) and can be a helpful check to see if your answer might be correct.
7. How can you calculate 79 x 20 quickly?
To calculate 79 x 20, you can use the value of 79 x 2 from the table. The process is:
First, recognise that 20 is the same as 2 x 10.
From the table, we know that 79 x 2 = 158.
Now, simply multiply that result by 10: 158 x 10 = 1580.
So, 79 x 20 equals 1580. This technique is useful for calculating multiples of 10.
