you multiply by ten for every number in change of pH. in this case it would be 10x10

The hydrogen ion concentration is multiplied or divided by a factor of 10 for every 1 point change on the pH scale.
Decrease from 6 to 4 = 2 steps on the pH scale.
pH 5 is 10 times as strong an acid as pH 6.
pH 4 is 100 times as strong an acid as pH 6.

You need to remember that the pH scale is a logarithmic one.
pH is the negative logarithm of the H+ concentration, that is why a 2 unit chage of pH is equivalent to a change in the concentration by a factor of 100.

while pH = 6, conc. of hydrogen ion = 10^ -6 (10 raised to the skill minus six) moles/litre. while pH = 4, conc. of hydrogen ion = 10^ -4 mole/ litre. subsequently the conc. of hydrogen ion has extra effective through one hundred fold.
