aidez moi svp c'est pour demain

A= 10 + 10² = 10 + 100 = 110
1) 
B= 10³ - 10 = 1000 - 10= 990
C= 10 x 10² = 10³ = 1000
D= 10⁴ + 10² = 10000 + 100 = 10100
E= 10³ / 10² = 10¹=10
F= 10⁵ + 10³ = 1000000 + 1000 = 1001000
G= 10⁶ - 10³ = 1000000 - 1000 = 999000
H= 10⁵ x 10² = 10⁷ = 10000000
I= 10⁴ / 10 = 10³ = 1000
J= 1/10 + 10 = 101 / 10
K= 1 /10³  x 10⁴ = 10¹ = 10
