165-(65+27)=? 231-(157+63)=? 211-(87+113)=? 742-(693+48)=?

1-ый пример.

165 - (65 + 27) = 73;

65 + 27 = 92;

165 - 92 = 73.

2-ой пример.

231 - (157 + 63) = 11;

157 + 63 = 220;

231 - 220 = 11.

Третий пример.

211 - (87 + 113) = 11;

87 + 113 = 200;

211 - 200 = 11.

4-ый пример.

742 - (693 + 48) = 1;

693 + 48 = 741;

742 - 741 = 1.
