SAMPLE QUESTIONS

Example Questions From the Test

- Multiply 7 by 3 and subtract 5, giving b = 16
- Subtract 5 from 7 before multiplying, giving b = 6
- Divide 7 by 3 and subtract 5, giving b = −8/3
- Subtract the product from 5, giving b = −16
- Divide by twice the length: w = A/(2l)
- Reverse the ratio: w = l/A
- Subtract the length: w = A − l
- Divide both sides by the length: w = A/l
- Invert the interest ratio: r = Pt/I
- Treat the product as a term to subtract: r = I − Pt
- Multiply by P but divide by t: r = IP/t
- Divide interest by both factors: r = I/(Pt)

These are 3 of the 16 real questions — the rest appear in the test. No sign-up needed to start.
