Math Practice Topic: Phrases to Algebraic Expressions

Description: Teaches you to translate from a phrase to an algebraic expression. Example: '3 added to x' becomes 'x + 3'. Warning: This topic can be very frustrating unless you pay close attention! This is a very literal topic. For example, '3 subtracted from x' only translates to 'x - 3', and '3 added to x' only translates to 'x + 3'. '3 added to x' does not translates to '3 + x' even though that is an equivalent expression. You can only succeed if you take the phrases very literally.

Adaptive Learning Progression: The algebraic expressions become more complex.

Sample Levels (out of 8)

Convert to an algebraic expression. Use / for division (write as fraction, not ÷).
When multiplying 2 numbers, use ( ). Example: write   28 × -14   as   28(-14).
Do NOT include leading 1's, example: write   -1x   as   -x.

1.
the product of -1 and n subtracted by thirty-five
2.
50 added to the product of negative one and j
3.
c subtracted by d

1.
the product of r and (the sum of n and 36) is greater than or equal to the quotient of 21 and j plus x
2.
the quotient of (thirty-six added to p) and m is equal to the sum of -1 times a and twenty-nine minus u
3.
the product of sixteen, w, and y is equal to the quotient of (j increased by 23) and five
