Question

Calculează suma a + b + c, știind că:
a) a = 546 + 304 – (560 : 7 × 3 + 10 × 27)
b) b = (515 – 490) × 25 – (808 : 4 + 100) × 2
c) c = 3 × [10 : 10 + 2 × (2 + 8 – 3)]

Answer 1

Buna!☆

a = 546 + 304 – (560 : 7 × 3 + 10 × 27)

a=546+304-(240+270)

a=546+304-510

a=340

b = (515 – 490) × 25 – (808 : 4 + 100) × 2

b=25×25-302×2

b=625-604

b=21

c= 3 × [10 : 10 + 2 × (2 + 8 – 3)]

c=3×(10:10+2×7)

c=3×(1+7)

c=3×8

c=24

a+b+c=340+21+24=385
