Calculating eight times -90

The idea behind calculating eight times -90 is to multiply the number -90 by 8. Multiplication by 8 can be thought of as adding -90 together eight times. For example, if -90 is 3, then adding 3 eight times (3+3+3+3+3+3+3+3) gives the same outcome as multiplying 3 by 8, which is the product expressed as -720. To perform this calculation, you take the variable -90 and use the expression (-90 * 8). This means you scale the value of -90 by eight, directly increasing it to eightfold its original size. The result -720 is a straightforward representation of this multiplication and can be applied to any real number value of -90, showing a fundamental arithmetic operation clearly and effectively.
