7
-7
nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9
5x + 2x - 7 = 0 Simplify 7x - 7 = 0 Add 7 to both sides 7x - 7 + 7 = 0 + 7 7x = 7 divide both sides by 7 x=1
When you add zero to a number, the number does not change. Ex: 5+0=5 5+2+0=7
Count by fives if is 0:05 or 0:00. If is 0:07 add 3 and then count by 5. If is 0:06 then add 4 then count by 5. If is 0:08 then add 1 and then count by 5. If is 0:09 then add 1 and count by 5. If is 0:04 then add 6 and count by 5. If is 0:03 then add 7 and count by 5. If is 2 add 8 and count by 5. If is 1 add 9 and count by 5.

When zero is added to any number, it remains unchanged. 5 + 0 = 5 6 + 0 = 6 7 + 0 = 7

Not possible ! The digits add as follows... 1+0+1 = 2 1+0+2 = 3 1+0+3 = 4 1+0+4 = 5 1+0+5 = 6 1+0+6 = 7 1+0+7 = 8
The number that will add to the given number and equal 0. What is add. inv of 7 ----- (-7) What is add. inv of -5 ---- 5 Simple way is to remember to change the sign fi you want the add. inverse.
add up all the numbers and divid by 11
