It is very hard to determine if your child has ADD or just tired, bored and not interested. Symptoms of ADD can be hyperactivity, not paying attention, trouble focusing, impulsive behavior and inability to sit still. Any concerns about your child's behavior should be discussed with his or her doctor.
You add all the numbers with + signs and subtract all that have minus signs.
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
if the signs are the same you must add its opposite.
Same rules as adding whole numbers with different signs.
You add as normal , pretend as if the signs weren't there,but the answer will be a negative!
Add them!
Temporarily ignore the signs and multiply or divide as usualIf signs of the two numbers to be multiplied or divided, add + sign to your answer. If signs are different, add - ( minus) to your answer.+ signs are optional-- a number without a sign is assumed to be positive.
To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)
same thing just add the money signs and decimal signs. hope that helps :)
Do the maths normally, ignoring the dollar signs. Then just add them in front of the answer at the end.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
Two integerss add to zero when their absolute values are equal and they have opposite signs.
