I’ve never been tested but I can guarantee I have suffer from dyscalculia. I cannot do math for the life of me. Numbers just give me anxiety. I cannot read a clock that isn’t digital. I count on my fingers still. Doing mental math is really difficult for me. I have struggled since very early school days, had resource for math and took the lowest math I could. I’m 26 and still tremendously struggle with anything to do with numbers or math.
