Integers Test - 9

The sign of the product of two like integers is positive, e.g., 5×4=20and − 2×−4=8

Use BODMAS rule & simplify. 124×4↓−3+118+2↓ =496−3+59=552

When a positive integer and a negative integer are added, we can get a positive or negative integer. ∴ Statement 1 is false.

And when two negative integers are added, we get a negative integer. ∴ Statement 2 is false

Dividend = Dividend * Quotient 

+ = - * -

N = {1,2,3.....}

W = {0,1,2,3...}

I = {-n...0,1,2,3.....n}

(−32)×(−4)×(−3)×0×(−6)=0as the product of any number and 0 is 0.

Case 1 : Asha scored = 26 marks Correct answers by Asha = 9 Let incorrect answers by Asha be x ∴ According to question, 9(4)+x(−2)=26 −2x=26−36⇒x=5 ∴ Incorrect answers by Asha = 5 Case 2 : Varun scored = 2 marks       Correct answers by Varun = 5            ; Let incorrect answers by Varun be y    ∴  According to question 5(4)+y(−2)=2⇒−2y=2−20⇒y=9 ∴ Incorrect answers by Varun = 9

1 is the smallest positive integer
