Verify the subtraction by digit sum (Bijank) method. 6 5 2 3 - 3 3 1

We need to verify the subtraction by digit sum (Bijank) method. Let us first solve the question, 6 5 2 3 - 3 3 1 6 1 9 2 Now, we will apply the bijank method of verification. Bijank of 6523 = 6 + 5 + 2 + 3 = 16 = 1 + 6 = 7 Bijank of 331 = 3 + 3 + 1 = 7 Bijank of 6192 = 6 + 1 + 9 + 2 = 18 = 1 + 8 = 9 Bijank of difference, 6192 is 9 and bjank of subtrahand, 331 is 7 . So, adding them we get, 9 + 7 = 16 = 1 + 6 = 7 , which is the same as the bijank of minuend. Thus verified.

Additive inverse of x - 1 x is

Additive inverse for a rational number is the same number with the opposite sign. Also, adding its additive inverse to a number results in zero. Additive inverse of a number is a number which when added to the given number gives zero. Let additive inverse of x - 1 x is f x . So, x - 1 x + f x = 0 ⇒ f x = 1 x - x Therefore, Additive inverse of x - 1 x is 1 x - x .

If a = − 8 , b = − 7 , c = 6 , verify that ( a + b ) + c = a + ( b + c ) .

Given, a = − 8 , b = − 7 , c = 6 , To verify that ( a + b ) + c = a + ( b + c ) . Consider LHS, ( a + b ) + c Now, put the values, we get: = ( − 8 + ( − 7 ) ) + 6 = − 15 + 6 = − 9 Similarly, Consider RHS: a + ( b + c ) Now, put the values, we get: = − 8 + ( − 7 + 6 ) = − 8 + ( − 1 ) = − 9 Therefore, LHS = - 9 = RHS Hence, verified. This also satisfies the property of associativity of addition.
