Professor David Atombiser walked into the dreary cavern and noticed jagged claw marks along the wall. “It’s very dark in here isn’t it”? He muttered to himself. “Look at those marks”, David said as he carefully inspected the scratches embedded in the wall. “Marvelous, absolutely marvelous!” he screeched in excitement. “But what is living here?” Professor David Atombiser questioned. There it was – the hulking form of the shrieking bear appeared in the dim light. “Truly extraordinary!” David exclaimed. It screeched and lurched towards him and with one swing of its mighty claws, Atombiser fell to the ground. Then the noise stopped, and the creature disappeared.
Which deal costs less per liter?
$32 for 4 liters
$8.50 for 1 liter
How I solved this problem:
I know for the first deal that 4 liters is $32, but how much does it cost for 4 liters of the second deal. To work this out I times 8.50 by 4. The answer is $34 so the first deal costs less per litre.
The loud music boomed inside my head and everything else became muffled. The disco had begun. I watched as eager classmates poured into the room like a rapid river, racing to get in first. Everyone was dancing to their hearts content, doing the worm, starting human trains and jumping up in the air. I heard the enjoyment and laughter buzzing around the stuffy room, which relieved me of my worries. I took a quick breath outside and came in to smell the mucky odour of sweat and barely kept my dinner from coming out. I came back in and joined in the fun dancing with my friends all night long, until bedtime.
The hurricane had torn up everything from the ground. Huts were demolished, palm trees were ripped out of the soil and hundreds of lives were lost. Khan Sibali had survived this natural disaster, now salvaging from the wreckages and searching for his lost family. His fishing village was flattened in an instant and only a handful had made it out alive. Khan sifted through the endless piles of debris, and from the corner of his eye he could see something glistening in the sunlight. He ran over to the shining object and found a glass bottle with a scroll inside it. It was his bottle of hope.
Question: Fill in the missing digits in the multiplication.
2 _ 6
_ 3 _
How I solved it:
Firstly I worked out what three times six was. The product is 18 so I put down the eight and carry the one over to the next column. Next I figure out what three times something plus one equals that ends in 3. To do this I go through my three times tables until I reach three times four, which is twelve, and then add one which is thirteen. I put the 4 in the middle of the 2 and 6 and carry the 1 over to the next column. Then, 3 times 2 equals 6, plus I add the 1 that was carried over and the product is 7. I put the 7 down in the answer.
I remember my great grandmother. She lived around the corner from me until she died when I was 8 years old. I can vaguely remember her short and round stature that resembled a matrushka doll and her accent – like a medieval vampire! She was Russian. I remember that she told me that when she was seventeen years old the Nazis invaded her country. She was taken and sent to prison camp in Germany and she never saw her family or friends ever again. I can’t even imagine what awful things would have happened. Then I remember how lucky I am.
Fill in the missing digits, using the digits one to nine.
1 _ 9
_ 5 _
First I worked out that 6 times 9 is 54, so I put the 4 down in the unit column and carried the 5 to the next column.
Then I had to figure out 6 x ? plus the 5 carried over and the answer needed to end in 5. So I figured out that 6 x 5 is 30 and if I then add the carried 5 the answer is 35. The 5 is already in the answer so I just have to carry the 3 over to the next column.
Then I figured out that 6 x 1 plus the carried over 3 equals 9.
Therefore the solution to the problem looks like this :
31 55 9
9 5 4
9 5 4
The rain had finally stopped and the countryside was speckled with large puddles, some more like small ponds. As I approached the largest, I could see its still, glassy surface perfectly reflecting the branches above. But as I drew closer I could see that the calm surface encased a tangled mess of forest debris that looked almost petrified; a reminder of the storms that had preceded just a few days before. Suddenly my peaceful thoughts were torn apart by a wave of panic. On the far side of the pond I could see a pair of protruding legs, rigid and perfectly upright.
Fill in the missing number.
36 ÷ ? = 4
How I solved this problem:
Since the product of the equation is 4, I went through my 4 times tables until I reached 36 which is 9 times 4. I then used division to make sure that the answer was correct.
The answer is 36 ÷ 9 = 4.
A violent storm was brewing deep inside the heart of the Caribbean Sea. Streaks of lightning cracked like whips and goliath 30-foot waves crashed into the ocean’s depths. Dropping from the dark, black sky was rain that pelted into the sea below like a hail of bullets. In amongst this chaos, one ship braved the elements. The cruelest and most ruthless pirate of all commandeered the vessel. His name was Captain Charles Bellamy. Crewmembers scrambled on deck as they tried hopelessly to save the ship but their reign of terror was finally about to end as they entered the eye of the storm.
