Calculează respectând regulile învăţate.
ja) 8 +5 * 120 + 3 * (2 + 4 x 6) - 15) - 3 = ?
/b) (150 + 12 x 8- (14 x 2-40:4)] * 10 = ?
(c) 5+ 5* [5 + 2 (5 + 25 * 1 - 24:4)] = ?​

Answer 1

Răspuns:

a) 8+5×120+3×(2+4×6)-15)-3= 8+600+3×(2+24)-15-3= 8+600-144-15-3=446

b) [150+12×8-(14×2-40÷4)]×10= [150+96-(28-10)]×10= ( 246-18)×10=228×10=2280

c) 5+5×[5+2×(5+25×1-24÷4)]= 5+5×[5+2×(5+25-6)]=5+5×(5+2×24)= 5+5×53=5+265=270
