Give expressions for the following cases. (a) 7 added to p                                                (b) 7 subtracted from p (c) p multiplied by 7                        (d) p divided by 7 (e) 7 subtracted from \[-m\]                       (f) \[-p\] multiplied by 5 (g) \[-p\] divided by 5                                    (h) p multiplied by \[-5\]                

Answer:

                (a) When 7 is added to \[p,\] then expression is \[p+7\]. (b) When 7 is subtracted from \[p,\] then expression is p \[-7\]. (c) When \[p\] is multiplied by 7, then expression is \[7\times p=7p\] (d) When p is divided by 7, then expression is\[\frac{p}{7}.\] (e) When 7 is subtracted from \[-m,\] then expression is \[-m-7\]. (f) When \[-p\] is multiplied by 5, then expression is \[-p\times 5=-5p.\] (g) When \[-p\] is divided by 5, then expression is \[\frac{-p}{5}.\] (h) When \[p\] is multiplied by \[-5,\] then expression is \[p\times -5=-5p.\]
