Answer: The answer is 6
Step-by-step explanation: In order to solve this problem you got to find a number that you takeaway 2 from to equal to 4. So for example if you have 6 apples and you takeaway 2 you will get 4.
Another way to solve this problem is this:
t-2=4
t -2+2=4+2 (the negative 2 and positive 2 cancels eachother out which equals zero)
t=6
