Write two different equations that can be used to solve this problem: a low of -4 degrees is predicted for tomorrow. If the tempeture is now 8 degrees by how much must it change?

I don't know because if I use these
-4+-4 it gives me -8 not 8, and if I use this -4+4 it gives me 0, so I don't know, what do you think?

To find the change in temperature, we can subtract the current temperature from the predicted temperature for tomorrow. Let's use the variable "change" to represent the change in temperature.
Equation 1: change = predicted temperature - current temperature
In this case, the predicted temperature for tomorrow is -4 degrees, and the current temperature is 8 degrees. Plugging these values into the equation, we get:
change = -4 - 8
change = -12 degrees
So, the temperature must change by -12 degrees.
Equation 2: change = |predicted temperature - current temperature|
In this equation, the absolute value notation (| |) is used to ensure that the result is always positive. The result represents the magnitude of the change, regardless of whether it is an increase or a decrease.
Using this equation, we can calculate the change in temperature as follows:
change = |(-4) - 8|
change = |-12|
change = 12 degrees
So, the magnitude of the temperature change is 12 degrees.
