place parentheses, if needed, to make each of the following equations true:
a.5+6.3=33
b.8+7-3=12
c.6+8-2/2=13
d.9+6/3=5
Try putting the parentheses around two numbers and figure out what you get. Don't forget that you do operations in parentheses first.
For example:
16-7+5=4
You could do:
(16-7)+ 5 = 4 OR
16-(7+5) = 4
Which one would be right?
Place parenthesis, if needed, to make each of the following equations true:
a) 5 + 6 * 3 = 33
To make each of the given equations true by adding parentheses if needed, we need to follow the order of operations. The order of operations is as follows:
1. Parentheses
2. Exponents (i.e., powers and square roots, etc.)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Let's go through each equation and add parentheses where necessary to make them true:
a.5+6.3=33
This equation is already correct, so no parentheses are needed.
b.8+7-3=12
To make this equation true, we can add parentheses around (8+7). This will ensure that the addition is performed before the subtraction.
So, the equation becomes:
(8+7)-3=12
c.6+8-2/2=13
To make this equation true, we can add parentheses around (2/2). This will ensure that the division is performed before the subtraction.
So, the equation becomes:
6+(8-(2/2))=13
d.9+6/3=5
To make this equation true, we can add parentheses around (9+6). This will ensure that the addition is performed before the division.
So, the equation becomes:
(9+6)/3=5
By adding parentheses where needed, we can make each of the given equations true.
