i don't understand this question. 2+(9*9)= ?
It means you need to add 2 to the quantity within parentheses.
2 + 81 = 83
2+9^2 the answer is 9*9+2=83
To understand this question, let's break it down step by step:
The equation is 2 + (9 * 9). The calculation inside the parentheses, 9 * 9, needs to be done first because multiplication takes precedence over addition.
To solve the multiplication, simply multiply 9 by 9:
9 * 9 = 81
Now we substitute the result of the multiplication back into the original equation:
2 + 81
Finally, we add 2 and 81 together:
2 + 81 = 83
So, the answer to the equation 2 + (9 * 9) is 83.
