55x3

55x3 refers to the mathematical operation of multiplying the number 55 by the number 3. This calculation results in the product 165. The number 55 is a composite number, meaning it has factors other than 1 and itself. Its prime factorization is 5 x 11. The number 3 is a prime number. The multiplication 55x3 can be broken down into (50 + 5) x 3, which equals (50 x 3) + (5 x 3), resulting in 150 + 15, and ultimately 165. Alternatively, one can perform the multiplication directly. Starting with the units digit, 3 multiplied by 5 equals 15. Write down the 5 and carry over the 1. Then, multiply 3 by the tens digit, 5, which equals 15. Add the carried-over 1 to this result, making it 16. Combining these digits gives 165. The number 165 is also a composite number, divisible by 3, 5, 11, 15, 33, and 55. The calculation 55x3 is a basic arithmetic problem commonly encountered in elementary mathematics education. It is a fundamental example used to teach multiplication principles.
