What is an Exponent?
Correct Answer
C. A small number to the right of a whole number to times that number that amount of times
Explanation
An exponent is a small number written to the right of a whole number, indicating that the whole number should be multiplied by itself that number of times. This is known as exponentiation. The exponent tells us how many times the base number should be multiplied by itself. For example, in the expression 2^3, the base number is 2 and the exponent is 3. This means that 2 should be multiplied by itself 3 times, resulting in 2 * 2 * 2 = 8.

7.
Is Zero odd or even?
Correct Answer
C. Neither
Explanation
Zero is considered neither odd nor even because it does not fit the criteria for either category. In mathematics, even numbers are divisible by 2, while odd numbers are not. Since zero is divisible by 2, it can be considered even. However, zero is also not positive, and odd numbers are typically positive. Therefore, zero does not fit the definition of either odd or even, making the correct answer "neither".
8.
Why is zero so important?
Correct Answer
C. Separates negatives from posotives
Explanation
Zero is important because it serves as a crucial separator between negative and positive numbers on the number line. It acts as the reference point, allowing us to distinguish between values that are less than zero and those that are greater than zero. Without zero, it would be challenging to understand and perform calculations involving negative and positive numbers.

More fractions. What is 4/6 x 3/5? And no, you are not allowed to Google 'How to multiply fractions'. Do it from memory
Correct Answer
A. 2/5
Explanation
To multiply fractions, we multiply the numerators together and the denominators together. In this case, 4/6 multiplied by 3/5 equals (4 x 3) / (6 x 5) which simplifies to 12/30. This can be further simplified by dividing both the numerator and denominator by their greatest common factor, which is 6. Therefore, 12/30 simplifies to 2/5.
