Question

2. Calculează, respectând ordinea efectuării parantezelor : (720:8+54) – 17x3 = = 1 799 + [3x(127 + 546 : 2) + 27:3] = 12 700 - [176 x 6 - 438:3+ (2+2x2)] = [3 000 – 3 x (366:3) + 7 899] – 2 005 = + 2 x[(0:90 +90:5) +123:3 - 10 ] +999:9 x 3= ​

Answer 1

Răspuns:

(720:8+54)-17x3

90+54-17x3

90+54-51

144-51

93

1799+[3x(127+546:2)+27:3]

1799+(381+273+9)

1799+663

2462

127000-[176x6-438:3+(2+2x2)]

127000-(1056-146+6)

127000-916

126084

[3000-3x(366:3)+7899]-2005

(3000-1098:3+7899)-2005

(3000-366+7899)-2005

10533-2005

8528

2x[(0:90+90:5)+123:3-10]+999:9-3

2x(0+18+41-10)+999:9-3

0+18+41-10+111-3
