Use Pоlyа's fоur-step prоblem-solving strаtegy аnd the problem-solving procedures presented in this lesson to solve the following exercise. Find the following sums without using a calculator or a formula (use may use a calculator for the final step). Hint: Apply the procedure used by Gauss (see the Math Matters on page 31). 1 + 2 + 3 + 4 + . . + 394 + 395 + 396 + 397 = [a] 1 + 2 + 3 + 4 + . . . + 541 + 542 + 543 + 544 = [b] 2 + 4 + 6 + 8 + . . . + 76 + 78 + 80 + 82 = [c]
