Answer 1

Răspuns:

a) 200+ 120 + (32 + 4x32)= 320 + (32+128)= 320+ 160= 480

b) [(1737 +678):7:3- 50 ]:5 x47= (2415 :7:3 -50): 5x47= (345 :3- 50):5x47=

(115 -50) :5 x 47= 65 : 5 x 47=13 x 47= 611

c) 136 + [ 34 + (87 +12) ] -14x13= 136 + (34+ 99) - 182= 136+133 - 182=269-182=

= 87

d) [181 - 174 + ( 845 - 650) ] :2 x 15= (7 + 195): 2x15= 202 :2 x 15= 101  x15=1515

e) 460 +1973 - ( 2846 - 5x 97)= 2433 - (2846- 485)= 2433 -2361=72
