x =  7
O =  4
M =  2
P =  1

### Step-by-step explanation:

$x={2}^{3}-1=7$
$O=x\mathrm{/}2+0.5=7\mathrm{/}2+0.5=4$
$M=\left(x-O\right)\mathrm{/}2+0.5=\left(7-4\right)\mathrm{/}2+0.5=2$
$P=\left(x-M-O\right)\mathrm{/}2+0.5=\left(7-2-4\right)\mathrm{/}2+0.5=1$ Did you find an error or inaccuracy? Feel free to write us. Thank you! Tips to related online calculators
