8x4-3=
8 x 4 is....?
Then subtract 3.
You should use parentheses to clarify whether you mean
8x(4-3) or (8x4)-3.
They are not the same.
If you were keying in the numbers and operations on a calculator, the multiplication would occur first, but writing it the way you have done is ambiguous.
Assuming you meant 8 multiplied by 4 minus 3, the correct calculation would be:
Step 1: Multiply 8 by 4: 8 x 4 = 32
Step 2: Subtract 3 from the result: 32 - 3 = 29
So, 8x4 - 3 equals 29.
