PRECISO PRA AGORA

Answer 1

a) ( +3 ) + ( +5 ) – ( - 2 ) = 10

b) ( -44 ) – ( +5 ) + ( -6 ) – ( -21 ) = −34

c) ( -6 ) + ( - 2 ) + ( +10 ) – ( -3 ) = 5

d) ( +3 ) – ( - 12 ) – ( -9 ) + ( -1 ) =23

Answer 2

Resposta:

Explicação passo-a-passo:

a) +3+5+2 = 8+2 = 10

b)-44-5-6+21=-44-11+21=-44+10=-34

c)-6-2+10+3=-8+13=5

d)+3+12+9-1=23
