$49$ $49$

Let's denote the number by $x$ $x$ .

Now, "the square of five less than the number is $24$ $24$ ".

This can be algebraically expressed as:

$\Rightarrow x - 5^{2} = 24$ $Rightarrow x - 5^(2) = 24$

or

$\Rightarrow x - 25 = 24$ $Rightarrow x - 25 = 24$

Let's add $25$ $25$ to both sides to solve for $x$ $x$ :

$\Rightarrow x - 25 + 25 = 24 + 25$ $Rightarrow x - 25 + 25 = 24 + 25$

$therefore x = 49$

Therefore, the number is $49$ .
