Решите примеры удобным и заполните поля : 1) 242 – 63 – 37 = 242 –  =  ; 2) 761 – 46 – 314 = 761 –  =  ; 3) 436 – 209 – 121 = 436 –  =  . вычислите, выбирая удобный порядок выполнения действий. 1) 87 – 49 – 27 = 60 –  =  ; 2) 120 – 64 – 36 = 120 –  =  ; 3) 88 – 53 – 18 = 70 –  =  ; 4) 43 – 15 – 25 = 43 –  =  .

1) 242 – 63 – 37 = 242 – 100 = 142 ; 

2) 761 – 46 – 314 = 761 – 360  = 401 ; 

3) 436 – 209 – 121 = 436 – 330 = 106 . 

1) 87 – 49 – 27 = 60 – 49  = 11; 

2) 120 – 64 – 36 = 120 –100  = 20  ; 

3) 88 – 53 – 18 = 70 – 53  = 17; 

4) 43 – 15 – 25 = 43 – 40 = 3  . 

1) 242 – 63 – 37 = 242 –  (63+37) = 242 - 100 = 142; 

2) 761 – 46 – 314 = 761 –  (46+314) = 761 - 360 = 401; 

3) 436 – 209 – 121 = 436 – (209+121) = 436 - 330 = 106. 

Вычислите, выбирая удобный порядок выполнения действий. 
1) 87 – 49 – 27 = 60 –  49 = 11; 

2) 120 – 64 – 36 = 120 – (64+36) = 120 - 100 = 20; 

3) 88 – 53 – 18 = 70 –  53 = 17 ; 

4) 43 – 15 – 25 = 43 – (15+25) = 43- 40 = 3 .
