Question

Evaluați expresiile următoare:
1. ((7/2-5/3)*(7%4=9%3)-(2*3-9/2))
2. 13+8
3. 4*5/7*2
4. 4*3/5

5. 6+3*5
6. 2+3*4/5

Answer 1

1. ((7/2-5/3)*(7%4=9%3)-(2*3-9/2))

((7/2-5/3) = 3-1 = 2

(7%4=9%3) = (3=0)  = 0 (Fals)

(2*3-9/2) = 6 - 4 = 2

Deci ecuatia initala e egala cu 2*0-2 = -2

2. 21

3. 20/7*2 = 2*3=6

4. 12/5 = 2

5. 6+15=21

6. 2+12/5 = 2 + 2 = 4
