= Calculating eight times -1.25
= (-1.25 * 8)
= -10
Explanation
The idea behind calculating eight times -1.25 is to multiply the number -1.25 by 8. Multiplication by 8 can be thought of as adding -1.25 together eight times. For example, if -1.25 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 -10. To perform this calculation, you take the variable -1.25 and use the expression (-1.25 * 8). This means you scale the value of -1.25 by eight, directly increasing it to eightfold its original size. The result -10 is a straightforward representation of this multiplication and can be applied to any real number value of -1.25, showing a fundamental arithmetic operation clearly and effectively.
