What are the rules to multiply two numbers?

Basic Rules of Multiplication:

• Any number multiplied by 0 is 0.
• Any number multiplied by 1 stays the same.
• When a number is multiplied by two we are doubling the number.
• When a whole number is multiplied by 10 we can simply write a 0 at the end (there is one zero in 10 because it is 1 × 10).

What happens when you multiply 2 binary?

4 Answers. It is trivial from the bit operations perspective. Multiplying by 2 is equivalent to a shift left by 1 bit, division is a right shift. similarly it is the same trivial to multiply and divide by any power of 2.

How do you multiply a binary number by 8?

Binary shifts

1. to multiply by two, all digits shift one place to the left.
2. to multiply by four, all digits shift two places to the left.
3. to multiply by eight, all digits shift three places to the left.
4. and so on.

What are the rules of binary?

There are 3 basic rules for adding binary numbers:

• 0 + 0 = 0.
• 0 + 1 = 1.
• 1 + 1 = 10. If the sum of 2 bits is greater than 1, we need to shift a column on the left. In decimal system, 1 + 1 = 2. Binary notation of 2 is 10 (1 * 2^1 + 0 * 2^0). So we keep 0 in the 1’s column and shift (carry over) 1 to the 2’s column.
