Answer 1

x:2=2:2=1

x:2+2=2:2+2=1+2=3

x-2=2-2=0

X × 100= 2×100=200

x+100= 2+100=102

X × 100+2= 2×100+2=200+2=202

x:2=8:2=4

x:2+2=8:2+2=4+2=6

x-2=8-2=6

X × 100=8×100==800

X × 100+2=8×100+2=800+2=802

x:2= 10:2=5

x:2+2=10:2+2=5+2=7

x-2=10-2=8

X × 100= 10×100=1000

x+100= 10+100=110

X × 100+2= 10×100+2=1000+2=1002

a×b=70×80=5600

a×b-b=5600-80=5520

a×b=90×40=3600

a×b-b=3600-40=3560

a×b=50×70=3500

a×b-b=3500-70=3430

a×b=60×80=4800

a×b-b= 4800-80=4720

a×b=70×90=6300

a×b-b=6300-90=6210

a×b=80×80=6400

a×b-b=6400-80=6320

u : v =27:3=9

u : v + v =9+3=12

u : v =42:6=7

u : v + v =7+6=13

u : v =63:9=7

u : v + v =7+9=16

u : v =54:6=9

u : v + v =9+6=15

u : v =36:4=9

u : v + v=9+4=13

u : v =24:3=8

u : v + v=8+3=11
