Hello --
This may be the dumbest question you've seen on here, so please bear with me.
I purchased a business/accounting calculator to tally expense receipts for my business. I programmed our sales tax rate (5% in Canada) and my goal is to subtract it from the total of all my receipts (as businesses are reimbursed this sales tax).

If I add the sales tax (Tax+), it works fine. But when I subtract sales tax from the total (Tax-) it provides an answer that is "close" to the correct answer, but not quite.
Eg. \$10.00 - 5% sales tax = \$10 - \$0.5 = \$9.50

But my calculator shows: \$10.00 - 5% sales tax = \$10 - \$0.4761904762 = \$9.52

Close but not correct. Any suggestions? I've included a picture of my calculator.

Thanks so much for your help!
Best,
Derek
