Answer 1

t) [6×10×100-(25×4-40)×5]-(10×10×7+120:3×35)=

=[60×100-(100-40)×5]-(100×7+40×35)=

=(6000-60×5)-(700+1400)=

=(6000-300)-2100=

=5700-2100=

=3600

u) [12×44+(750+450:6+27:9):6]:2+4=

=[528+(750+75+3):6]:2+4=

=[528+(825+3):6]:2+4=

=(528+828:6):2+4=

=(528+138):2+4=

=666:2+4=

=333+4=

=337

v) [12×33+4×(950-250×3+4)]:3+47×13=

=[396+4×(950-750+4)]:3+611=

=[396+4×(200+4)]:3+611=

=(396+4×204):3+611=

=(396+816):3+611=

=1212:3+611=

=404+611=

=1015
