Найдите значение суммы a + b + c при указанных значениях a, b и c:
а) a = 17, b = −23, с = −9;
б) a = −33, b = −18, c = 26;
в) a = 25, b = −19, c = 50;
г) a = −12, b = −20, c = −19.
a = 17, b = −23, с = −9
a + b + c = 17 + (−23) + (−9) = 17 + (−32) = −15
a = −33, b = −18, c = 26
a + b + c = −33 + (−18) + 26 = −51 + 26 = −25
a = 25, b = −19, c = 50
a + b + c = 25 + (−19) + 50 = 6 + 50 = 56
a = −12, b = −20, c = −19
a + b + c = −12 + (−20) + (−19) = −32 + (−19) = −51
