Answer 2

Răspuns:

• $0,34*10+1,2=3,4+1,2=4,6$

• $8,04*10+3,67=80,4+3,67=84,07$

• $4,75*10-3,9=47,5-3,9=43,6$

• $3,46*10-9,85=34,6-9,85=24,75$

• $1,53*10-24=15,3-24=-8,7$

• $6,74*10+357=67,4+357=424,4$

• $1,53-10-24=-8,47-24=-32,47$

• $6,74-10+357=-3,26+357=353,74$

N-am inteles daca la ultimele puncte este * 10 sau - 10 si am facut pentru amandoua .
