My ex isn't good with numbers but nevertheless she has a master in education. She has helped many, many children with learning deficiencies. For lots of people, the math is a significant barrier.

Very true, I don't want to presume of people ability.
I do believe though that being able to do a subtraction and a multiplication, even if both roughly approximated, for an adult in our current societies (as in not living like an hermit in the woods) is a very useful skill, even if just not get scammed while going shopping or to know how many items one can buy.
Again this isn't reciting the first 100 digits or Pi or doing (12345-12158) * 0.3223 in your head in .1s, rather it's about (~12300-12100) * .3 and knowing you should put about ~20 bucks in, not 1 buck nor 100, and if you want to be "safe" or "kind" to others you put 30 bucks, a very safe upper bound and be done with it.
OK maybe the 1st time you have to write it down. Maybe you even put your phone out and use the calculator but it should after a couple of times become pretty straightforward.
edit: if you don't have dyscalculia I think it's worth couple of seconds in your life because the ability does improve with practice and it's helpful in plenty of places.
