This week we mostly studied for the mid-term. One thing I did learn was how exponents on negative numbers work with brackets and no brackets. If there are no brackets on the negative number, the exponent only multiplies by the number, making the final answer a negative no matter what. If brackets are on the number, you have the whole number to multiply. If the exponent is an even number, the answer will be positive. If the number is odd, then the answer will be negative.
