Question

If p=-2,q=-1 and r=3, find the value of. a)p-q-r​

Answer 1

Answer:

(-4)

Step-by-step explanation:

p = (-2)                       ∴p-q-r = (-2)-(-1)-3

q = (-1)                                    =  -2+1-3

r = 3                                       =   (-4)

Answer 2

Solution :-

Substituting p = -2, q = -1 and r = 3 in the given expression, we get :

$\begin{gathered} (-2) - (-1) - 3 \\ = -2 + 1 - 3 \\ = -4 \end{gathered}$

Hence, answer is $\large\pink{\bf{\fbox{-4}}}$
