Describe the mistakes.
3 x 8 - 4 x 5 = 100
24 - 20 = ?
4, but they're asking what's the mistake that was made in the problem. Because 100 isn't the correct answer.. I'm really stumped on this. :(
What is 24 - 20?
24 - 20 = 4
I still don't get it..?
3 x 8 = 24
4 x 5 = 20
24 - 20 = 4
The correct answer is 4, not 100.
The mistake in the equation "3 x 8 - 4 x 5 = 100" lies in the order of operations. According to the order of operations (also known as PEMDAS or BODMAS), multiplication and division should be done before addition and subtraction.
To correctly solve the equation, we need to multiply before subtracting. Let's break it down step by step:
First, we do the multiplication: 3 x 8 = 24 and 4 x 5 = 20.
Now, the equation becomes: 24 - 20 = 100.
Next, we subtract: 24 - 20 = 4.
So, the correct solution to the equation should be 4, not 100.
