today is my birthday please help me only math Aryabhatta please answer this question

Q.1) a + ( b + c ) = ( a + b ) + c
➭ Substitute the values,
-» -25+ [20+ (-10) = [(-25) +20] + (-10)
Solve the RHS with brackets first,
Solve the LHS with brackets first,
-» -25 + 10 = [(-25) +20] + (-10)
Add the integers in LHS,
-» -15= [(-25) +20] + (-10)
-» -15=(-5)+ (-10) Add the integers in RHS,
-» -15= -15
Comparing both sides,
LHS = RHS
Thus, verified.
-------------------------------------
2) a × (b + c) = a × b + a × c
Solution: Substitute the values,
-» -25 x [20+ (-10)] = (-25) × 20 + (-25) × (-10)
Solve the LHS with brackets first,
-» -25 x 10 = (-25) 20+ (-25) (-10)
Multiply the integers,
-» 250 = (-25) x 20 + (-25) × (-10)
Solve the RHS using BODMAS rule,
-» -250 = -500 + 250
Add the integers,
-» -250 = -250
Comparing both sides,
LHS = RHS
Thus, verified.
