Select the correct combination of mathematical signs to replace the * signs and balance the given equation.
13 * 7 * 12 * 4 * 15 * 65

The correct combination of mathematical signs to balance the equation is +, +, ÷, ×, =.

To verify this combination, replace the asterisk (*) signs in the given expression from left to right with the signs +, +, ÷, ×, and =:

$13+7+12÷4\times 15=65$

We evaluate the Left-Hand Side (LHS) using the standard order of operations (BODMAS/PEMDAS: Division and Multiplication first, followed by Addition):

Step 1: Division
Perform the division operation $12÷4$:

$12÷4=3$

Substituting this back into the expression gives:
$13+7+3\times 15$

Step 2: Multiplication
Perform the multiplication operation $3\times 15$:

$3\times 15=45$

Substituting this back into the expression gives:
$13+7+45$

Step 3: Addition
Add the remaining numbers from left to right:

$13+7=20$

$20+45=65$

Since LHS = RHS ($65=65$), the given equation is correctly balanced.
