What is the end of a multiplication?
A multiplication sentence is made up of 3 numbers, a multiplication sign, × and an equals sign, =. The number before the × sign tells us how many groups we have. The number after the × sign tells us how many are in each group. The number at the end, after the equals sign is the total number of items.
What are the 4 types of multiplication?
The Four Types of Multiplication Properties
- Commutative. The commutative property for multiplication states that when you multiply two or more numbers together, the order in which you multiply them will not change the answer.
- Associative.
- Identity.
- Distributive.
How do you find the last number?
To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit. To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10.
What are the first 5 multiply?
The multiples of 5 are the numbers that are generated when 5 is multiplied by any natural number….What are the multiples of 5?
| 5 × 2 = 10 | 5 multiplied by 2 to get 10 |
|---|---|
| 5 × 4 = 20 | 5 multiplied by 4 to get 20 |
| 5 × 5 = 25 | 5 multiplied by 5 to get 25 |
| 5 × 11 = 55 | 5 multiplied by 11 to get 55 |
How do you find the last digit of a number?
Example: 2*2 = 4*2 = 8*2 = 16*2 = 32 last digit in 32 is 2 that means after multiplying 4 times digit repeat itself. So the algorithm is very simple . Since number are very large we store them as a string. Take last digit in base a.
What will be the last digit of a^B?
Last digit of a^b will be ldigit\%10. Below is the implementation of above algorithm.
What is the last digit of the exponent b\%4=0?
Here b is very large. If b\%4==0 that means b is completely divisible by 4, so our exponent now will be exp = 4 because by multiplying number 4 times, we get the last digit according to cycle table in above diagram.
