This week i learned about how to add and subtract radicals. At first I thought that adding radicals together would look like this: 1√2 + 4√3 = (1 + 4) √(2 + 3) = 5√5. I thought that you had to add the radicands together under one root sign, but my table group explained to me that this is how it works: 1√2 + 4√2 = (1 + 4) √2 = 5√2. The radicals do not get added together if the radicand is the same, you have to add or subtract the coefficients first and then keep the same root because its being multiplied by the coefficients.
