First, we open the parentheses and change the sign accordingly.
Since there are only positive numbers inside the parentheses, multiplying by minus will give us negative numbers:
Now we group the X factors:
Now we obtain:
\( 100-(5+55)= \)
The minus sign acts like multiplying by -1. Just like (-1)×(4b+3x) = -4b-3x, the distributive property requires you to multiply each term by the negative.
Then you'd get positive results! For example: 7x-(-4b-3x) = 7x+4b+3x. Remember: negative times negative equals positive.
Like terms have the same variable and exponent. In this problem, 7x and 3x are like terms because they both have 'x'. The term 4b is different and stays separate.
No! You must follow the order of operations. The parentheses and subtraction are given in the problem, so you must distribute the negative sign first, then combine like terms.
They're exactly the same! Addition and subtraction can be rearranged using the commutative property. Both expressions equal the same value.
