Para resolver este tipo de problemas tenemos que tener en cuenta el orden:
1. 3×5+(18÷6)+2×3=
=15+18÷6+(2)(3)
=15+3+(2)(3)
=18+(2)(3)
=18+6
=24 -- Respuesta.
2. 5+3-4(6*7)-(18÷3)
=8−4(6)(7)−18÷3
=8−(4)(42)−18÷3
=8−168−18÷3
=−160−18÷3
=−160−6
=−166 --- Respuesta.
3. (72÷9)+3-5-(4×5)
=8+3−5−(4)(5)
=11−5−(4)(5)
=6−(4)(5)
=6−20
=−14 -- Respuesta.
4. 100-52-(56÷7)+13
=48−56÷7+13
=48−8+13
=40+13
=53
5. 6-4×(54÷6)+18-(2×3) 6−(4)(9)+18−(2)(3)
6−(4)(9)+18−(2)(3)
=6−36+18−(2)(3)
=−30+18−(2)(3)
=−12−(2)(3)
=−12−6
=−18
6. 7×(48÷8)+(27÷3)-5×2=
=(7)(6)+27÷3−(5)(2)
=42+27÷3−(5)(2)
=42+9−(5)(2)
=51−(5)(2)
=51−10
=41
