1) add, equal
2) multiply, equal
3) subtract, equal
M=log I / S
if M=6, 6=logI/S and then 10^6=I/S, so we get I=S <span>x 10^6, we assume that
</span>A=S x 10^6
if M=8, so, 8=logI/S and then 10^8=I/S, so we get I= S x 10^8=A=S x 10^6x10^2
since A=S x 10^6, so I= <span>A x10^2, </span><span>an earthquake with a magnitude of 8 is 10² stronger than an earthquake with a magnitude of 6.</span>
Answer:
To add two integers with the same sign, add their absolute values. The sum is :
- <u>Positive</u> if both integers are positive
- <u>Negative</u> if both integers are negative
Jacki didn’t subtract 12 from 8 correctly he was suppose to get a negative and not 12
