Negative exponents indicate that the number for which the exponent applies to should be placed under one. Ex: 2^(-3) also can be expressed as 1/(2^3) or 1/8. So, to eliminate the negative exponent, simply place the number (and the accompanying exponent) under one to make a fraction.
When multiplying a number by a negative number, the result is always negative. Therefore, 2 times a negative 2 is -4. This can be calculated by multiplying 2 by -2, resulting in -4 as the product.
A negative multiplied by a negative gives a positive, so the answer is 4.
Negative four (-4).-2 - 2 = -4
