(8 + n) * 4 =
For example, the two examples below shows the importance of 'Order of Operation':
(8 + 5) * 4 = 52
8 + 5 * 4 = 28
x+7=y
17x+(1+x)
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
0.5
The sum is the total when numbers are added together, the product is the total when they are multiplied.
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
90
divisor
It is n + 14.
n+3 the sum of a number and three means a number plus three.
The algebraic expression is n + 100, where n is the unknown number.
y = x +8 where x is the number
the product of 8 and the sum of 10 and -7
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
x+7=y
2(n+7)
