30×15-30×5-299= 30×(15-5)-299=

= 30*10-299= 300-299=1

Answer 2

To solve this expression, you need to use the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to this rule, you need to perform multiplication and division before addition and subtraction, and within multiplication and division, you need to perform them from left to right.

Applying this rule to the expression you provided, we get:

30×15 - 30×5 - 299 = 450 - 150 - 299

Now we can perform the subtraction from left to right:

= 300 - 299

= 1

Therefore, the solution to the expression 30×15-30×5-299 is 1.
