I can do maths but it’s an effort and I don’t retain it. A friend who was a USGS hydrologist and then a prof at UC Berkeley could actually think in mathematical terms. When we were talking about some watery thing, like flow patterns around a meander bend, he’d stop and jot down an equation.
I’d say “You mean like this?” and wave my hands around.
He’d say “Exactly!” and we’d both laugh.
