The old rule of thumb is "take the sign away from the larger number, subtract the smaller number from the larger, and put back the sign"
So, looking at 2-4, 4 is the larger magnitude number and 2 is the smaller. The negative sign is on the 4, so park it somewhere temporarily and write the new problem as (larger - smaller); that is, 4 - 2, which anyone can do. The answer is 2, then put back the minus sign that was temporarily set aside, giving you a final answer of -2.
Or, try 7 - 19. 19 is larger, so park the minus sign and compute 19-7 = 12. Put back the minus sign and the answer is -12. Believe it or not, it's what you're doing with a "normal" subtraction problem, it's just that you don't generally write the + sign. For example, if you had 9 - 5, the 9 is the larger number and has a (hidden) + sign in front of it. So, it's really +9 -4. Park the + sign, subtract 9 - 5 = 4, and put the + sign back to get +4.
4
The sum of 20 and -4 is +16, while the product of 4 and -2 is -8. The answer to the question is therefore -2.
4 + 2 = 6
2 and 2 because 2+2 = 4 and 2*2 = 4
A sum of 4 is more likely. Out of the 36 possible outcomes with a pair of 6-sided dice, only one will have a sum of 2 {1-1}. Three of the possibilities sum to 4. {1-3, 2-2, 3-1}
the sum is example 2+2=4, 4 is the sum
The answer to an addition problem is called the sum.The sum of 2 plus 2 is 4.
6
Sum = Addition 2 + 2 = 4
The sum of 2 + 2 is 4.
5 Check the intensity of the object. The sum will be 5.
4
The sum is 6.
sum = 2+4+ 6 might work.
the sum of 2 plus 2 is 4/2+2=44
The sum of 20 and -4 is +16, while the product of 4 and -2 is -8. The answer to the question is therefore -2.
The quotient of 2 and the sum of 30 and -4 is negative thirteen.
