PLZ HELP TROLL ANSWERS GET REPORTED MAKE IT UNDERSTANDABLE Match each expression to its value.
lbvjy [14]

Answer:

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12

Step-by-step explanation:

Lets solve the expressions one by one

<u>1. 7-5</u>

we can see that it is simple subtraction. A smaller number is being subtracted from a large number.

So the answer is 2

<u>2. -7+5</u>

There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.

In this case, 7 is larger and has negative sign, the answer will be -2

<u>3. -7-5</u>

When there are two numbers with minus sign they are added but the answer has the minus sign with it.

So the answer will be: -12

<u>4. 7-(-5)</u>

When minus is multiplied with minus it converts to positive

So

= 7-(-5) = 7+5 = 12

Hence,

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12
