1. ICE BREAKER MONDAY TASK

2. WHAT IS THE NEXT NUMBER? 13 57 91 11 31 51 ?

3. EACH LETTER IS A DIFFERENT DIGIT 0,1,2,3,4,5,6,7,8,9 HINTS E=3 B=7 A=4

4. EACH LETTER IS A DIFFERENT DIGIT 0,1,2,3,4,5,6,7,8,9 (1)7+7=14 so G=1. (2) S+L can’t be 3 since 2 and 5 are the lowest unused digits (3)In the 10s position S+L=13 means 8+5 or 5+8. (4)In the one’s position 3+5 = 8 means L=5,S=8 (5)This forces M=9

5. EACH LETTER IS A DIFFERENT DIGIT 0,1,2,3,4,5,6,7,8,9 HINTS D=3 L=7 A=8

6. EACH LETTER IS A DIFFERENT DIGIT 0,1,2,3,4,5,6,7,8,9 RULES (1)2,0,1,5 are already used (2)o is zero! (3)CAN IT BE DONE?

7. EACH LETTER IS A DIFFERENT DIGIT 0,1,2,3,4,5,6,7,8,9 The thousands column must have a carry since c cannot equal 2. N + 0 must give 0 which must be 10 so N must be 9 and there is another carry from the 10s column. M+1 with a carry needs more so the ones column must also generate a carry. This forces c to be 3. That means M +1 plus the carry from the ones column has to be at least 14 which is impossible!
