Răspuns:

e 2 400 + (345 × 10 − 23 × 67) =2400 +(3450-1.541)= 2400+ 1999= 4399

f.9 567-6x (456 x 3 - 24 x 12) + 3 010 =9567- 6x( 1368- 288)+3010=9567-6480+ 3010=6097

g. (81:9 x 3+3): (6x4:2+27:9) = 30: 15=2

h. 100-6 x 9 + (5+5:5-5x5:5)= 100-54+1=45

i.7x8-4x6: (50:10 x2-3x8:6): 2:2:1 =56-24:(10-4):1=56-4=52
