(-15)+(-15)+(-15)+(-15)
Step-by-step explanation:
1. The multiplication shown in the problem above is:
4(-15)
The product is -60
4(-15)=-60
2. The multiplication above could indicate that:
- The number -15 is added 4 times.
- The number 15 is added 4 times and then is multiplied by -1.
- The number -4 is added 15 times.
- The number 4 is added 15 times and then is multiplied by -1.
Keeping these on mind, you can conclude that the correct options are the third option and the last option:
(-1)(15+15+15+15)=(-1)(60)=-60
(-15)+(-15)+(-15)+(-15)=-15-15-15-15=-60
