This is an editorial by Leigh Bortins published in World Magazine:

It does add up
Just as we would encourage an illiterate adult to take reading lessons, we should encourage innumerate adults to take math lessons. Would Margie Haack (World, April 12) as easily admit, "I can't read the words," as she unembarrassedly claims, "I can't do the math"?

I am sorry math is taught so poorly in this country and that otherwise intelligent adults don't have the confidence to pursue the completion of their education. As a math tutor, I find our culture's flippant attitude toward innumeracy to be expected. But I am disappointed when Christians think it is acceptable to be ignorant of an entire realm of God's truth.
