$\bf b)~ ~\blue{ 48}$

$\bf c)~~ \red{\bf ~9~}$

Explicație pas cu pas:

Buna !

$\bf a) ~13\cdot 4-72:2 =$

$\bf 52-72:2 =$

$\bf 52 - 36=$

$\purple{\boxed{\bf ~16~}}$

$\bf b)~ 96:4\cdot3-48:2 =$

$\bf 24\cdot3-48:2 =$

$\bf 72-24=$

$\blue{\boxed{\bf 48}}$

$\bf c)~924-5\cdot(45:3+7\cdot24)=$

$\bf 924-5\cdot(15+7\cdot24)=$

$\bf 924-5\cdot(15+168)=$

$\bf 924-5\cdot 183=$

$\bf 924-915=$

$\red{\boxed{\bf ~9~}}$

Mult succes !
