Вычислите удобным способом 83*234-83*334,-29*53-29*47,736-536-82,743-(243-311),-73+(93+46)

83 * 234 - 83 * 334 = 83 * (234 - 334) = 83 * (-100) = -8300;-29 * 53 - 29 * 47 = -29 * (53 - 47) = -29 * 6 = -174;736 - 536 - 82 = (736 - 536) - 82 = 200 - 82 = 118;743 - (243 - 311) = (743 - 243) - 311 = 500 - 311 = 189;-73 + (93 + 46) = (93 - 73) + 46 = 20 + 46 = 66/
