| Cool Math Trick |
| This week's cool math trick is called the 25 trick. When you have 2 digits multiplied by 25 like this: 25x12=_____ Then what you do is forget about the 25 and divide the other # by 4. Write down the 3 as the first digit of your answer. 25x12=_3___ Finally, add two zeros after the 3. 25x12=_300_ If there are any remainders then each remainder will add 25 to the answer. 25x5=_125_ Pretty neat, huh? Now you try it! |
