Some relationships have been expressed through symbols which are explained below :
$\text{O} = $ greater than
$\Delta = $ not equal to
$\text{X} = $ not less than
$+ = $ equal to
$\phi = $ not greater than
$\Sigma = $ less than
What does $\text{P} \; \Sigma \; \text{Q} \; \Sigma \; \text{R}$ imply?
- $\text{P} \; \Delta \; \text{Q} \; \phi \; \text{R}$
- $\text{P} \; \phi \; \text{Q} + \text{R}$
- $\text{P O Q} + \text{R}$
- $\text{P O Q X R}$
