a) 1000-25×25+35×35:5=1000-625+245=620

b) 2015+100÷4×75-123:1=2015+1875-123=3767

c) 5×(50×20-12×56)-800×2=5×(1000-672)-1600=5×328-1600=1640-1600=40

d) 150×(1015-975)-(975-88÷8)=150×40-(975-11)=6000-964=5036

A) 1000-625+1225:5=

=1000-625+245=620

B) 2015+25*75-123=

=2015+1875-123=3767

C) 5*(1000-672)-1600=

=5*328-1600=40

D) 150*40-(975-11)=

=6000-964=5036
