1+2 is 'one plus two' or 'one and two' or 'two added to one'.
3 - 4 is 'three minus four' or 'three less four'
5 *12 is 'five times twelve' or 'five multiplied by twelve' or 'five twelve times'
5 ÷ 23 is 'five divided by 23' or '23 (goes) into five'

1/2 = one half
2/3 = two thirds
187/1000 = one hundred and eighty-seven thousandths

x² or any other power = x squared, x cubed , x to the fourth (power)
vx... = square root of x, cube root of x, fourth root of x

?f(x)dx — I didn't get that far in mathematics.
