4x4+4x4+4-4x4=?
20
4x4
To find the solution to the equation 4x4 + 4x4 + 4 - 4x4, we can follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right):
Step 1: Perform the multiplication operations first, from left to right.
4x4 = 16
4x4 = 16
-4x4 = -16
After performing these multiplications, the equation becomes:
16 + 16 + 4 - 16
Step 2: Now, perform the addition and subtraction operations, from left to right.
16 + 16 = 32
32 + 4 = 36
36 - 16 = 20
Therefore, the solution to the equation 4x4 + 4x4 + 4 - 4x4 is 20.
