What do you understand by unary and binary operators? (b) What results will MATLAB produce on the Command Window if the following are typed >>-52, >>(-5)2, >>10-6/2, >>5*4/2+3?

In MATLAB, a\b is equivalent to b/a.

1\verb|\2 = \frac{2}{1} = 2

The result is:

$$\boxed{2}$$

MATLAB follows the order of operations (PEMDAS/BODMAS). Exponentiation ^ has higher precedence than unary negation -. So, $5^2$ is calculated first, then the negation is applied.

$$-5^2 = -(5^2) = -(25) = -25$$

The result is:

$$\boxed{-25}$$

Parentheses change the order of operations. Here, the negation is applied to 5 first, then the result is squared.

$$(-5)^2 = (-5) \times (-5) = 25$$

The result is:

$$\boxed{25}$$

Division / has higher precedence than subtraction -.

$$10 - 6/2 = 10 - (6/2) = 10 - 3 = 7$$

The result is:

$$\boxed{7}$$

Multiplication * and division / have the same precedence and are evaluated from left to right. Addition + has lower precedence.

$$5*4/2+3 = (5 \times 4)/2 + 3 = 20/2 + 3 = 10 + 3 = 13$$

The result is:

$$\boxed{13}$$
