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.
2 subtracted from s
2.
the quotient of 17 and -13 →
3.
the quotient of c and v

1.
the product of a and (c plus g) is less than negative thirty-three increased by 28 minus 43 →
2.
17 times (twenty-two added to n) is greater than s increased by t increased by 40 →
3.
the quotient of the product of r and z and negative forty-four is less than or equal to the product of -39 and h subtracted by t
