Question

efectueaza 4x8+(174+249-68)x0= ,(2x3x1+72:9):7=, 543-4x10-10x10-(129+174)=, (36:4+25:5-7x2)x8x9= , (81:9)+(7x8-6x9)-(301-292)= ,200-100:10+1x7x8x0-(45+45)=, 100-(549-421-9x9+3x7)=, (264-198+367)x2x0x5=

Answer 1

4 x 8 + 355 x 0=
=32+355x0
=32

(2 x 3 x 1 + 72:9):7=
=(6+8):7
=14:7
=2

543-40x10-10x10-(129+174)=
=543-400-100-303
=43-303
=-260

(36:4+25:5-7x2)x8x9=
(9+5-14)x8x9=
=(14-14)x8x9
=0x8x9
=0

(81:9)+(7x8-6x9)-(301-292)=
=9+(56-54)-11
=9+2-11
=11-11
=0


200-100:10+1x7x8x0-(45+45)=
200-10+0-90=
=190-90
=100

100-(549-421-9x9+3x7)=
=100-(549-421-81+21)
=100-(128-81+21)
=100-(47+21)
=100-68
=32

(264-198+367)x2x0x5=
=(66+367)x2x0x5
=433x2x0x5
=866x0x5
=0x5
=0
