Let's answer this question slowly: Would you hire someone with dyscalculia to do surveying work?
Dyscalculia is a learning disability in math. People with dyscalculia have trouble with math at many levels. Surveyors work with elements of geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. Geometry and trigonometry are types of advanced mathematics. So the answer is no.
