Accuracy of adding tax rates

I have always LOVED this app! It makes it so much easier to total up my customer orders at my parties or when Im on the run. But here lately Ive been noticing my totals are off when I enter my customer orders. Come to find out its because the sales tax is not adding up correctly. Its shorting my totals. Can this please be fixed?! Otherwise I cant continue to use it because it is causing me to loose money since I wont go back to my customers & say "oh sorry, my app didnt give me the correct total so you owe me more money.
