Răspuns:

Explicație pas cu pas:

A) 24+68+76+32 = (24 + 76) + (68 + 32) = 100 + 100 = 200

B) 224+29+32+76+71+24 = 224 + 32 + (29 + 71) + (76 + 24) = 256 + 100 + 100 = 456

C) 90+900+100+10 = (90 + 10) + (900 + 100) = 100 + 1000 = 1100

D) 450+327+550+673 = (450 + 550) + (327 + 673) = 1000 + 1000 = 2000

E) 444+999+556+1 = (444 + 556) + (999 + 1) = 1000 + 1000 = 2000

F) 25+58+175+142 = (25 + 175) + (58 + 142) = 200 + 200 = 400
