Don’t do that. It’s letting the computer do the work your eyes and brain are supposed to be doing.
Evaluate the expression visually and write in only the outcome for each question, True, or False.
Like before, write out the two expressions separately and evaluate each one. Remember order of operations from maths? The same rules apply here, only they are called precedence (same meaning).
Multiplication | same operation but inverse
Subtraction | same operation but inverse
So in this example,
-1 > 1 and (3+3) == 9
-1 > 1
(3 + 3) == 9
We know that negative 1 is not greater than 1, so that is False. We can stop there, but let’s go ahead and evaluate the other operand…
3 + 3 => 6
We know that 6 does not equal to 9, so that too is False. No matter, we already solved the AND expression when we found the first False.
Let’s look at the next expression, broken into its two operands…
-(-(-(-2))) == -2
4 >= 16 ** 0.5
From maths we know that raising a negative number to an even exponent yields a positive, and an odd exponent yields a negative. Those four negative signs at the same as
-1 ** 4, which is
1 * 2 yields
2 is not equal to negative 2, so that expression is False, and we can stop there. But let’s look at the second expression, anyway…
Exponents come first so,
16 ** 0.5 => 4. (4 is the square root of 16). The second expression yields True, but that does not matter since the first one was False.
