Xi = all of the scores associated with a given variable: therefore, xi means add all x variables in the set together, xi = ( 1 + 2 + 3 + ) I means find the square root of the x (calculator) 2 means square each x and then add together. ( i)2 means find the sum of 1 + 2 + 3 a(cid:374)d the(cid:374) s(cid:395)ua(cid:396)e the total. Order of operations this (cid:396)efe(cid:396)s to the o(cid:396)de(cid:396) i(cid:374) which calculatio(cid:374)s i(cid:374) a(cid:374) e(cid:395)uatio(cid:374) should occu(cid:396) bedmas. When adding or subtracting decimals, line up the decimals and add or subtract as usual. When multiplying two decimals, the decimal place in the answer should total the amount of decimal places in both numbers (i. e. , . 22 x . 2 = . 044)
