Addition & Subtraction of Binary Numbers

Write the component statements of the following compound statements and check whether the compound statement is true or false (i) Venus is the smallest and Jupiter is the largest planet of solar system. (ii) India is a country and Asia is a continent. (iii) Commutative law holds for addition and subtraction of rational number. (iv) Additive inverse exists for natural number and rational number (v) 32 is a multiple of 2, 3 and 4.

A) In multiplication or division, the final result should retain only that many significant figures as are there in the original number with the least number of significant figures. B) In addition or subtraction the final result should retain only that many decimal places as are there in the number with the least number of decimal places.

Assertion - Vector addition of two vector is always greater then their vector subtraction. Reason At theta =90^(@) , addition and subtraction of two vector are equal .

Write these fractions appropriately as additions or subtractions: Figure Figure

Discuss the commutativity of the binary operation * on R defined by a * b=a-b+a b for all a , b in R , where on RHS we have usual addition, subtraction and multiplication of real numbers.

Discuss the commutativity and associativity of the binary operation . on R defined by a*b=a-b+a b for all a , b in R , where on RHS we have usual addition, subtraction and multiplication of real numbers.

Which of the following is true? * defined by (a) a*b=(a+b)/2 is a binary operation on Z (b) * defined by a*b=(a+b)/2 is a binary operation on Q (c) all binary commutative operations are associative (d) subtraction is a binary operation on N

A : Physical relations involving addition and subtraction cannot be derived by dimensional analysis. R : Numerical constants cannot be deduced by the methos of dimensions.

We have learnt about fractions and decimals alongwith the operations of addition and subtraction on them, in the earlier class
