Answer 3

Sure, let's solve this math problem in different ways:

Method 1: Use the Order of Operations (PEMDAS)

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Following this order, we should first solve anything inside parentheses, then exponents, then multiplication and division, and finally addition and subtraction.

So, according to PEMDAS, we should first do the multiplication inside the parentheses, and then multiply the result by 6:

(20+30)6 = 506 = 300

Therefore, (20+30)*6 equals 300.

Method 2: Distributive Property of Multiplication

The Distributive Property of Multiplication says that we can distribute a number or expression to each term inside parentheses. Using this property, we can rewrite the expression as:

(20+30)6 = 206 + 30*6

Then, we can multiply each term by 6:

206 + 306 = 120 + 180 = 300

Therefore, (20+30)*6 equals 300.

Method 3: Mental Math

We can also use mental math to solve this problem. First, we can add 20 and 30 to get 50. Then, we can multiply 50 by 6:

50*6 = 300

Therefore, (20+30)*6 equals 300.
