Quick Challenges

Number Explorer

What is the 10th Fibonacci number?

✓ 55 (1,1,2,3,5,8,13,21,34,55)

Geometry

A triangle has angles 90° and 45°. What is the third angle?

✓ 45° — angles of a triangle sum to 180°

Statistics

If the mean of 5 numbers is 12, what is their sum?

✓ 60 (sum = mean × count = 12 × 5)
