Question

12 ? 3 = 4 x 4 = ?

20 x 3 = ?

90 x 1 = ?

123 - 123 = ?

10 x 9 = ? / 9 = ?

12 - 9 = ? x 9 = ?

23 - 5 = ?

123 + 12 = ?

1000 - 200 = ?

333 - 111 = ?

Answer 1

12 : 3 = 4 x 4 = 16

20 x 3 = 60

90 : 1 = 90

123 - 123 = 0

10 x 9 = 90 : 9 = 10

12 - 9 = 3 x 9 = 27

23 - 5 = 18

123 + 12 = 135

1000 - 200 = 800

333 - 111 = 222

Answer 2

\(20.3=60\)

\(90.1=90\)

\(123-123=0\)

\(10.9=\frac{810}{9}=90\)

\(23-5=15\)

\(123+12=135\)

\(1000-200=800\)

\(333-111=222\)
