These kids have no clue.
I cook. I sew. I do some home repair. I budget. I shop.
I use all kinds of math, though not calculus (thank God), on a daily basis.
Don't be so hard on yourself, knowing what'll fit in your trunk, refrigerator, or what not, is a subjective form of multi-variable calculus.
And knowing about how close you can have something on your stove to the hot spot without catching fire would be a form of partial differential equations.
So now you can tell people you are a math genius!
