# 20 Most Recent Texas Instruments BA-II Plus Calculator Questions & Answers

### My TI BA II Plus is returning incorrect answers for TVM problems... Is this common and can it be fixed?

Let's see, 10% interest per year on \$100 for one month. That's 10/12 of a percent interest on \$100 is \$0.83, added to \$100 is \$100.83 (with a bunch more 3s at the end). Clearly this is the correct answer. What answer are you expecting? The future value at the end of one year instead of one month?
