Most everyone learns to multiply the same way. We stack two numbers, multiply every digit in the bottom number by every digit in the top number, and do addition at the end. If you’re multiplying two two-digit numbers, you end up performing four smaller multiplications to produce a final product.

In algebra and higher mathematics, letters are used to stand for a number that is not yet known or specified. So x might be a number instead of an operator. So, to avoid confusion, a new symbol was needed for multiplication. Some people use the dot to mean multiplication; more nowadays use the asterisk.

the symbol (⋅), (×), or (∗) between two mathematical expressions, denoting multiplication of the second expression by the first. In certain algebraic notations the sign is suppressed and multiplication is indicated by immediate juxtaposition or contiguity, as in ab.

3x is a coefficient with the variable of x. For example: 3x+ 4. X3 must mean x with the exponent of 3.

To double-check our work, multiply 7.6667 by 6 to see that it equals 46.

The first 10 multiples of 46 are 46, 92, 138, 184, 230, 276, 322, 368, 414 and 460. Therefore, Sum of first 10 multiples: 46 + 92 + 138 + 184 + 230 + 276 + 322 + 368 + 414 + 460 = 2530.

45 = 1 x 45, 3 x 15, or 5 x 9. Factors of 45: 1, 3, 5, 9, 15, 45.

To double-check our work, multiply 15 by 6 to see that it equals 90.

The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.

The answer to the question: What is 90 divided by 3 is as follows:

1. 90 / 3 = 30. Instead of saying 90 divided by 3 equals 30, you could just use the division symbol, which is a slash, as we did above.
2. 90 ÷ 3 = 30.
3. 90 over 3 = 30.
4. 90⁄3 = 30.

91 = 1 x 91 or 7 x 13. Factors of 91: 1, 7, 13, 91.
