Step-by-step explanation:
∴ Addition is associative. ∴ Subtraction is not associative. ∴ Multiplication is associative. ∴ Division is not associative.
...
Associativity for Integers.
Operation Commutative True / False
Addition a + (b + c) = (a + b) + c True
Subtraction a − (b − c) = (a − b) − c False
Answer:
1 + (2 + (-3)) = 0 = (1 + 2) + (−3)
1 × (2 × (−3)) =−6 = (1 × 2) × (−3)
x= 0.6
5
12x12-13x13=b2
144-169=b2
25
=5
Both sides of the equation are exactly same.
It means regardless the value of x the equation is true.
The equation has infinitely many solutions.
