Question
A = -4 + (-6) – (-10)
B = 150 + 25 – (-25) + (-225) C = 18 + (-12) + (-6) + 13
D = (-3 + 10) – (4 – 15) – (-12 – 8) E = -23 – [40 – (3 – 19)]
F = 33 – 23 + 27 – 57 + 38 – (-12)
Merci

A = -4+(-6)-(-10)
A = -4-6-(-10)
A = -4-6+10
A = -10+10
A = 0
B = 150+25-(-25)+(-225)
B = 150+25+25+(-225)
B = 150+25+25-225
B = 200-225
B = -25
C = 18+(-12)+(-6)+13
C = 18-12+(-6)+13
C = 18-12-6+13
C = 31-18
C = 13
D = (-3+10)-(4-15)-(-12-8)
D = 7-(4-15)-(-12-8)
D = 7-(-11)-(-12-8)
D = 7-(-11)-(-20)
D = 7+11-(-20)
D = 7+11+20
D = 18+20
D = 38
E = -23-[40-(3-19)]
E = -23-[40-(-16)]
E = -23-[40+16]
E = -23-[56]
E = -23-56
E = -79
F = 33-23+27-57+38-(-12)
F = 33-23+27-57+38+12
F = 30
Voilà !
