please help it 3[1-6(2-9)] simplifyis due tonight
2-9 = -7
6 * -7 = -42
1 - (-42) = 43
3 * 43 = 129
I think that's the answer.
thank you so much
To simplify the expression 3[1-6(2-9)], we can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). Let's break it down step by step:
1. Start by simplifying the expression inside the innermost parentheses:
2-9 = -7
2. Next, substitute the result into the expression:
3[1-6(-7)]
3. Simplify the next set of parentheses:
-6(-7) = 42
4. Substitute the result back into the expression:
3[1-42]
5. Subtract 42 from 1:
1 - 42 = -41
6. Finally, multiply the result by 3:
-41 * 3 = -123
Therefore, the simplified form of 3[1-6(2-9)] is -123.
