Explicație pas cu pas:
l) [25+2×(49-27):4]:12= (25+2×22:4):12=36:12=3
m) (1+0+222-200) × 2- 45= 23×2-45= 46-45=1
n) ...=1 ( orice numar la puterea 0 e 1)
o) (45⁵⁴+1) ×1/(1+45⁵⁴)= (45⁵⁴+1)/(1+45⁵⁴)= 1
p) 1+0=1
r) 806+1768+26=2600
s) 100+5×(5+20)-125= 100+125-125=100
t) 50+10×29-100= 50+290-100=240
u) 9999-808-101= 9292
v) 11:11+ (125×2+10):12= 1+ (250+10):12= 1+260:12= 1+ 21,(6)
la ultimul cred ca a fost exercitiul gresit
