Four times a number x equals 4x.
Eight does not go into four any whole number of times. In division, the number being divided (in this case, four) should be greater than the divisor (in this case, eight) for the division to result in a whole number quotient. Since eight is greater than four, it cannot go into four any whole number of times.
4 times a number added to 7 times the number equals 33
To increase a number by four times, you would multiply the number by 4. For example, if you have the number "g", to increase it by four times you would calculate 4g.
The sum of four times a number and twice the same number can be represented mathematically as (4x + 2x), where (x) is the number. Combining the terms, this simplifies to (6x). Therefore, the result is six times the number.
Twenty-one times greater than four would be 21 x 4, which equals 84.
4n-5 (Which is four times a number minus 5)
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).
