This showed CAS OR does not have higher precedence: 0×(0+1) = 0
But, it does not illustrate precedence rule, result is same as left to right: 0×0+1 = 1

Quote:I thought I’d also try it using Python syntax in the CAS. There, “True or False and False” evaluates to “False”.

This showed CAS AND does not have higher precedence: 1+0×0 = 1
CAS only does left to right: (1+0)×0 = 0
