Where do I put the parentheses and brackets to make this true
15÷3×5+4×8=40
(15÷(3×5)+4)×8=40
To correctly place the parentheses and brackets to make the equation true, let's follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):
The original equation is: 15 ÷ 3 × 5 + 4 × 8 = 40
Step 1: Start with the multiplication and division from left to right.
15 ÷ 3 = 5
5 × 5 = 25
The equation now becomes: 25 + 4 × 8 = 40
Step 2: Continue with the remaining multiplication.
4 × 8 = 32
The equation now becomes: 25 + 32 = 40
Step 3: Finally, perform the addition.
25 + 32 = 57
After following the order of operations, we found that the equation evaluates to 57 instead of 40. Based on this, it is not possible to place parentheses or brackets in a way that makes the equation true.
