Meet DON Direction of number

Meet DON DON looks like this when he’s stood still

Positive -1 +1 DON looks like this when facing the positive direction

Negative -1 +1 DON looks like this when facing the negative direction

DON can show us how to use directed numbers

First a calculation for DON to show us

7 + -3 = First a calculation for DON to show us

7 + -3 = Easy First a calculation for DON to show us

7 + -3 = This number tells me where to stand -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = This number tells me where to stand -10 -8 -6 -4 -2 +2 +4 +2 +4 +6 +8 +10

+7 7 + -3 = The first sign tells me which way to face -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = The first sign tells me which way to face I need to face the positive direction +7 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = The first sign tells me which way to face I need to face the positive direction +7 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = The second sign tells me whether to go forwards or backwards +7 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = The second sign tells me whether to go forward or backward The sign is minus so +7 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = The second sign tells me whether to go forward or backward The sign is minus so I need to go backwards. +7 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

+7 7 + -3 = I need to go backwards by 3 -10 -8 -6 -4 -2 +2 +4 +6 +8 +2 +4 +6 +8 +10

+7 7 + -3 = I need to go backwards by 3 Ok lets do it… -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = Back by 1 +6 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = Back by 2 +5 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = Back by 3 +4 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = We end up at +4 +4 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = We end up at +4 7 + -3 = +4 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10

7 + -3 = We end up at +4 7 + -3 = 4 +4 -10 -8 -6 -4 -2 +2 +4 +6 +8 +10
