Answer 1

90000000  +  70000000                  =  160000000

80000000  -  100000  +  30000        = 79930000

700000  +  40000 - 60000               = 680000

300000  +  40000  +  2000 - 10000  = 328000

Answer 2

90000000+70000000=160000000

80000000-100000+30000=79930000

700000+40000-60000=680000

300000+40000-2000+10000=328000
