5×9 - 2×4=37

1) 5×9=45 2) 2×4=8 3) 45-8=37

14:(2×7)=1

1) 2×7=14 2) 14:14=1

18:6:3=1

1) 18:6=3 2) 3:3=1

12:6×9=18

1) 12:6=2 2) 2×9=18

14:2×7=

1) 14:2=7 2) 7×7=49

16:4×2×2=16

1) 16:4=4 2) 4×2=8 3) 8×2=16

18:(6:3)=9

1) 6:3=2 2) 18:2=9

Answer 2

Let's break it down step by step:

1. $2 \times 9 + \frac{45}{9} = 5 \times 9 - 2 \times 4$

   $18 + 5 = 45 - 8$

   $23 = 37$

   This step seems to be incorrect.

2. $14 \div (2 \times 7) = 18 \div 6 \div 3$

   $14 \div 14 = 3$

   This step is correct.

3. $12 \div 6 \times 9 = 14 \div (2 \times 7)$

   $2 \times 9 = 14 \div 14$

   $18 = 1$

   This step is incorrect.

4. $16 \div (4 \times 2 \times 2) = 18 \div (6 \div 3)$

   $16 \div 16 = 18 \div 2$

   $1 = 9$

   This step is incorrect.

It looks like there might be some errors or misunderstandings in the calculations. If you have any specific questions about certain steps or if there's anything you'd like me to clarify, feel free to ask!
