Question

Ma ajutati la niste ex. la matematica?
(100-56:8x9-1x5):8x4=
(236-200-6x3):9x7-14=
120-(7x5+2x7):7x8=
23+(4x5-64:8):4x7=
(23-15)x2+(9x4-5x6):3=

Answer 1

1.(100-56:8x9-1x5):8x4=
=(100-7x9-5):8x4=
=(100-63-5):8x4=
=32:8x4=
=4x4=
=16
2. (236-200-6x3):9x7-14=
=(236-200-18):9x7-14=
=(36-18):9x7-14=
=18:9x7-14=
=2x7-14=
=14-14=
=0
3.120-(7x5+2x7):7x8=
=120-(35+14):7x8=
=120-49:7x8=
=120-7x8=
=120-56=
=64
4.23+(4x5-64:8):4x7=
=23+(20-8):4x7=
=23+12:4x7=
=23+3x7=
=23+21=
=44
5.(23-15)x2+(9x4-5x6):3=
=8x2+(36-30):3=
=16+6:3=
=16+2=
=18
Sper ca te-am ajutat :*

Answer 2

(100-56:8x9-1x5):8x4=
(100-7x9-5):8x4=
(100-63-5):8x4=
32:8x4=
4x4=16

(236-200-6x3):9x7-14=
(36-18):9x7-14=
18:9x7-14=
2x7-14=
14-14=0

120-(7x5+2x7):7x8=
120-(35+14):7x8=
120-49:7x8=
120-7x8=
120-56=64

23+(4x5-64:8):4x7=
23+(20-8):4x7=
23+12:4x7=
23+3x7=
23+21=44

(23-15)x2+(9x4-5x6):3=
8x2+(36-30):3=
16+6:3=
16+2=18
