Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information." Comment recorded on the 2 May 'Starter of the Day' page by Angela Lowry, : "I think these are great! So useful and handy, the children love them.

When multiplying or dividing negative numbers remember this:
Same Signs \( \rightarrow \) Positive Answer
Different Signs \( \rightarrow \) Negative Answer
Example 1: Same signs (a positive multiplied by a positive) gives a positive answer:
\( 12 \times 6 = 72 \)
Example 2: Different signs (a positive multiplied by a negative) gives a negative answer:
\( 12 \times (6) = 72 \)
Example 3: Different signs (a negative divided by a positive) gives a negative answer:
\( (12) \div 6 = 2 \)
Example 4: Same signs (a negative divided by a negative) gives a positive answer:
\( (12) \div (6) = 2 \)
