(c)101+278=278+101=397, 397-278=101=397-101=278
(2) PERFORM THE FOLLOWING SUBTRACTIONS AND CHECK YOUR RESULT BY CORRESPONDING ADDITION
(a)13407-10999=2408, check: 10999+2408=13407
(b) 100000-95673=4327, Check: 95673+4327=100000
(C)3030301-676767=2353534, Check: 2353534+676767=3030301
(d)80093000-989996= 79103004, 79103004+989996=80093000
(3) Solution: 378-(152+79)= 378-231=147
