7times (4times10 - the 7 is squared) +4
is it this?
7*(4*10-72)+4
then
7*(40-49)+4
7*(-9)+4
-63+4
-59
yes
To solve this expression, you need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). Let's break down the expression according to PEMDAS:
1. Start with the exponent operation:
7 squared means 7 * 7 = 49.
2. Next, perform the multiplication operation within the parentheses:
4 * 10 = 40.
3. Now, substitute the value of the squared number:
49 - 40 = 9.
4. Finally, perform the remaining multiplication and addition:
7 * 9 = 63.
63 + 4 = 67.
Therefore, the value of the expression 7 * (4 * 10 - 7^2) + 4 is 67.
