十四、观察下面的算术题,作出解答。(10分)
1. Each letter represents(代表) a number. Write down the numbers.

A= ______ B= ______ C= ______ D= ______
2. It's a simple sum(简单的算术题). Can you work out which number is represented(代表) by every letter?

A= ______ N= ______ S= ______ W= ______ E= ______ R= ______

1. $ A = 3 $ $ B = 6 $ $ C = 4 $ $ D = 1 $
2. $ A = 1 $ $ N = 4 $ $ S = 2 $ $ W = 8 $ $ E = 5 $ $ R = 7 $
解析 1. 本题题干是:每个字母代表一个数字。写出这些数字。
观察算式可以发现 $ 2C = 8 $，$ C = 4 $。假设 $ A $ 为 $ x $，$ D $ 是 $ 4 - x $，$ B = 9 - x $，列算式: $ (4 - x) + (9 - x) = 7 $，$ x = 3 $，所以 $ A = 3 $ $ B = 6 $ $ C = 4 $ $ D = 1 $。
2. 本题题干是:这是一个简单的算术题。你能算出每一个字母代表的数字吗?
观察算式可以发现 $ R \times R = 49 $，$ R = 7 $ 或 3。但 3 只有乘以 3 时，积的个位才是 9，其余字母不能再为 3。所以 $ R = 7 $。逆向思维，$ 999999 \div 7 = 142857 $，所以 $ A = 1 $ $ N = 4 $ $ S = 2 $ $ W = 8 $ $ E = 5 $。
