Multiplicand times multiplier equals product. If the expression has a variable, the numerical factor of the variable is the coefficient.
If the variable x represents the number: 5x + 3ParenthesesExponentsMultiplyDivideAddSubtractAlways remember this
k = 10 3k = 30 When a number appears next to a variable (like "k") it usually means multiply the number times the variable.
The expression for "forty times m" can be written as 40m. In this expression, the number 40 is being multiplied by the variable m. This means that you are taking 40 and multiplying it by whatever value m represents. This expression simplifies to the product of 40 and m.

If a certain number of hours is "x", then 8 times as much would simply be "8x".
x = 6n/42 x = n/7
The expression can be thus: 3x-3 whereas x is the unknown variable
