Answer:
Ok, so the equation would be 6-2*12+5. The answer to that is -13.
Step-by-Step Explanation:
You would use PEMDAS. First, you multiply 2 and 12 and that's 24. Now your equation is 6-24+5. Then you subtract 6 and 24 and that's -18. Now your equation is -18+5, and the answer to that equation is -13. I hope this helps you!!
-7.89, -5.23, -5.22, 34.98, 51.02, 51.22
Lets break it down:
(Rational numbers consist of whole, numbers, integers, and fractions)
Negatives come after 0, so the greater the number gets, the less value it has, opposite of positive numbers.
So since -7.89 is the greatest negative number, it will have the least value.
Hope this helps!
