A natural number greater than 1 that has no positive divisors other than 1 and itself.- Which of 2, 3, 5, 9 are prime numbers?
Show answer
2, 3, and 5. (9 = 3 times 3, so it is composite.)- A number is divisible by 3 if what is true about its digits?
Show answer
The sum of its digits is divisible by 3.- A number is divisible by 9 if what is true?
Show answer
The sum of its digits is divisible by 9.- Define the Greatest Common Divisor (GCD).
Show answer

Show answer
The smallest positive integer that is divisible by two or more given numbers.- When you divide 17 by 5, the remainder is?
Show answer

Show answer
1/4- If a quantity increases from 50 to 60, what is the percent increase?
Show answer
20% (because (60 - 50) / 50 = 10 / 50 = 0.2 = 20%)- If the ratio of boys to girls is 3:2 and there are 15 boys, how many girls are there?
Show answer
10 girls (because 3 : 2 = 15 : x, so x = 10)- What is the average (arithmetic mean) of 5, 10, and 15?
Show answer
10 (because (5 + 10 + 15) / 3 = 30 / 3 = 10)- Simplify 2^5.
Show answer
32 (because 2 times 2 times 2 times 2 times 2 = 32)- What is the square root of 144?
Show answer
12 (because 12 times 12 = 144)- What does PEMDAS/BODMAS tell you?
Show answer
The order in which to perform operations: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right).- What is the absolute value of -7?
