Answer 2

1. $73-58+29-4 = 102-62 = 40$

2.

$24:8*3*4:6 =\\3*3*4:6 =\\3^{2} *4:6=\\9*4:6=\\36:6=6$

3. $30+32:8+8*7-100:10=30+4+56-10=80$

4.

$20-(3*5-2+3):(26-9*2) =\\20-(15-2+3):(26-18)=\\20-16:8=\\20-2=18$

5. $89+64:8*7-28:7*4=89+56-16=129$

6. $815-24:2:2=815-6=809$

7. $50:10:5+90:9=1+10=11$

8.

$12+6:(3+9:3)=\\12+6:(3+3)=\\12+6:6=\\12+1=13$

9.

$21-21:7*(4-5:5) =\\21-21:7*(4-1)=\\21-21:7*3=\\21-9=12$
