We use scientific notation when either the questions asks for it or when the number is really long or really short...
Answer:
70
Step-by-step explanation:
I suppose its 70 because... 7 + 3 = 10
and 70 + 30 = 100...so the SUM is 100...yet minus 30 would be 70...so
70 is the bigger number...
please let me know if this was right...
hope I helped!

Answer:
The main difference is that one has the equal sign before it while the other has it after.

Step-by-step explanation:
The answer is 2/15. When you multiply the equation it’s 2/15 and it’s already simplified.
