Déjà vu:

Math isn’t for everybody.

I’ve noticed after years of working with people whose focus isn’t math, that slipping by three or six decimal places is considered by them to be a minor error, easy to make and hard to notice.

This is why we all did story problems in our heads as kids. Right?

If it was or effected their paycheck, they’d notice PDQ.

To be fair, we all make mistakes, and she fessed up to doing so under public scrutiny.

Good name for, anything.

We’re just not very good at teaching practical math.

I’m going to guess the original person was treating millions like ‘apples’. Practical math users know that units cancel, like 8 foo / 4 foo = 2 (not 2 foo). But people who hate math and avoid it tend to think of the big numbers as kind of a decorator, like a color, because they don’t grasp it so 8 million / 4 million = ( 8 / 4 ) million = 2 million.
