The following is an excerpt from a telephone conversation between Ben Simpson, president of Main Street Co., and Tami Lundgren, owner of Reliable Employment Co.:

Ben:Tami, you're going to have to do better job of finding me a new computer programmer. That last guy was great at programming, but he didn't have any common sense.

Tami:What do you mean? The guy had a master's degree with straight A's.

Ben:Yes, well, last month he developed a new financial reporting system. He said we could do without manually preparing an end-of-period spreadsheet and financial statements. The computer would automatically generate our financial statements with "a push of a button."

Tami:So what's the big deal? Sounds to me like it would save you time and effort.

Ben:Right! The balance sheet showed a minus for supplies!

Tami:Minus supplies? How can that be?

Ben:That's what I asked.

Tami:So, what did he say?

Ben:Well, after he checked the program, he said that it must be right. The minuses were greater than the pluses....

Tami:Didn't he know that Supplies can't have a credit balanceit must have a debit balance?

Ben:He asked me what a debit and credit were.

Tami:I see your point.
