Answer to Problem 115A

Exponents should be same while adding or subtracting otherwise the results will not be correct.

Explanation of Solution

The exponents should be same for adding or subtracting two numbers because the exponential terms indicates how many decimal places a decimal is required to move but if exponents are not same or different, the numbers will not be added or subtracted correctly.

Conclusion

Exponents should be same while adding or subtracting otherwise the results will not be correct.
