Equivalent statements Quiz
6 questions · easy to harder · Discrete Math · score and step-by-step answers
How it works
- 6 questions, about 18 minutes (a timer counts down; you can hide it). Solve it right here: no sign-up.
- 6 questions have choices. For the others you type the answer: a number like 4, −2, 7/2 or 3.5, or for example x = 4, x = 2 or x = −3, (3, 5), 2x + 1. Use ^ for powers (x^2) and sqrt for √. Any form with the same value counts (7/2 = 3.5).
- One question at a time: Back, Next, Mark for review and the question list at the bottom. A calculator is on the screen.
- At the end: your percent and grade, every question right or wrong, why a wrong choice is wrong, and its step-by-step solution. Then practise the lesson with new questions.
