**Negative exponent**

A negative exponent is a base that is on the wrong side of the fraction line. The students need to flip the base to the other side.

For example, x^{–2} means x^{2}, but underneath, as in 1/x^{2}.

Each negative exponent can be expressed as a positive reciprocal. A reciprocal is a fraction where the numerator & denominator change places.

**A negative number is any number less than zero**.

Negative numbers are expressed with a negative sign.

For instance: -4 is four less than zero. If the students add & subtract negative numbers, they either move to the right or the left of the number line.

When they subtract a negative number they move to the left of the number line as it’s the same as adding a positive number. If they add a negative number, they move to the right because it’s the same as subtracting a positive number.

**How to solve negative fraction exponents**

When the students multiply a negative number by a positive number or vice versa, the number will be negative. If they multiply two positive numbers or two negative numbers, the result will be positive.

**Some Rules need to follow:**

- If multiplying like bases, add powers together
- If dividing like bases, subtract powers

- If raising power by another exponent, multiply powers together

- If raising several variables by a power, distribute power to each base
- If raising several variables by a power, distribute power to each base
- Any base raised to the power of zero becomes 1

- If changing a negative exponent to a positive one, flip it into a reciprocal.
