{chaves 2+ [(3-1)-(2-1)]+5 }chaves
5+{8+2-[3+(5-4+1)]-1}
50+24=(10+2-8).3
40- {10+3 [2+(3+4).2]:4} +1

Answer 1

{ 2+ [(3-1)-(2-1)]+5 }
{ 2+ [2- 1]+5 }
{ 2+ 1 +5 }
3 + 5
8

5+{8+2-[3+(5-4+1)]-1}
5+{ 10-[3+( 1 +1)]-1}
5+{ 10-[3+2]-1}
5+{ 10- 5 -1}
5+{ 10 - 6}
5+ 4
9

50+24=(12-8).3
74 = 4 * 3
74 = 12

40- {10+3 [2+(3+4).2]:4} +1
40- {10+3 [2+7.2]:4} +1
40- {10+3 [2 + 14]:4} +1
40- {10+3 *16:4} +1
40- {10+3 * 4} +1
40- {10+ 12 } +1
40- 22 +1
