-4 -3 -2 -1 0 1 2 3 4 5 6 7 8

this is pretty easy what you do is start from the -3 and add 8 and you'll get the answer of 4 because in this equation you just take away the plus sign and then solve

8 + (-4) is really 8 - 4, so your answer would be 4

2007-09-06 17:57:03 · answer #6 · answered by Jenny 3 · 0 2

8 +(-4) is the same as saying 8-4 seeing as the plus and minus signs together make a minus sign. if there were two plus signs then it would be 8+4=12. if there were two minus signs e.g. 8-(-4) it would be 8+4= 12. Then if it was 8-(+4) it would equal 4.

look when u have different signs and a + and a - it becomes a - so the problem becomes 8-4 which is equal to 4

Subtract the number with the lowest absolute
value , in this case -4 , from the number with the highest absolute vale. Then keep the sign of the number with the highest absolute value. Since the absolute value of -4= 4 and the absolute value of 8=8. You would subtract 4 from 8 and keep the understood positive sign belonging to eight.
Remember to place this sign in front of your answer.

Open the bracket and it will equal to 8 - 4 = 4
remember:
for ... +(-...) will be equal to -
...-(-...) will be equal to +
e.g. 2+(-1) = 2-1 =1
4-(-1) = 4+1 = 5
