Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on finding percentage % After the lesson if there is a part you don't understand  feel free to comment Fig 1. We all probably know that when we hear percentage we think of 100. So here are 5 amazing tricks that can help to find percentage of some numbers without the use of a calculator. So let's begin We'll start with some tips 1. Tip -1- 15% of 300 =45 Step 1- Calculate 10% 300/10 = 30 Step 2- Calculate 5% of the answer from Step 1. 5% of 30= 15 Step 3- Add step 1 and 2 30+15= 45 Fig 2. 2. 5% of numbers -1- 5% of 60= 3 Step 1- Divide the number by 10 60/10 = 6 Step 2- Divide the number from Step 1 by 2 6/2 = 3 Fig 3. 3. 20% of numbers   -1- 20% of 255= 51 Step 1- 20% = (100/5)% Step 2- 255/5 = 51 Step 3- 5=10/2 Step 4- Divide the number by 10 255/10 = 25.5 Step 5- Multiply the number from Step 4 by 2 25.5 × 2=51 -2- 20% of 255 = 51 Step 1- Divide the number by 10 255/10 ...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on squaring of some numbers After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin 1. Square numbers ending in 5            .1. 35 2  = 1225 Step 1- Multiply the first digit by the first digit plus one 3 ×(3+1)=12 Step 2- Write the number 25 next to the result from Step 1 12_ 25 Fig 2. 2. Square numbers between 10 and 19       .1.  14^2 = 196 Step 1-  Add the number to the ones digit 14+4=18 Step 2- Multiply the number from Step 1 by 10 18 × 10 =180 Step 3- Square the ones digit number  4^2 = 16 Step 4- Add Step 2 and 3 180+16=196 Fig 3.  3. Square numbers between 40 and 49 -1- 48^2= 2304 Step 1- Subtract the number from 50 50-48=2 Step 2- Subtract the result(from Step 1 ) from 25 25-2=23 Step 3- Square the result from Step 1 ( if the result is a single digit put a zero in front of it) 2^2=04 Step 4- Place the result from Step 3 ne...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on Wait for it  5  Arithme-tricks😉 on multiplication of some digits After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin  1. Multiplication of two digit number by 11                           -1- 35 × 11 Step 1- Add both digits of the two digit number 3 + 5 = 8 Step 2- Place the result in between both digits 3_8_5 = 385 Fig 2. -2- 78 × 11= 858 Step 1 - Add both digits of the two digit number 7+8= 1 5 Step 2- Carry the one when the result is greater than nine 7+ 1= 8 Step 3- Place the result in between both digits  8_5_8=858 Fig 3. 2. Multiply by 9:       -1- 56 ×9= 504 Step 1- Multiply the number by 10: 56× 10 =560 Step 2- Subtract the original number from step 1 560 - 56= 504 Fig 4. 3. Multiply numbers between 11 and 19     -1- 14 ×18= 252 Step 1- Add the larger number to the rightmost digit of the other number 18 + 4=22 Step 2- Put a zero at the end of the...

Hello ALGEBROS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on Wait for it 5 algebatic terms After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's begin 1. X×X×X= x3 That is if X multiplies itself 3 times  It becomes X raised to the power 3 The same way if you have something like 3x ×3x ×3x  You'll get 27x3 That is 27x raised to the power 3 The same way if 3 multiplies itself 2 times it will give you 3 raised to the power 2 Fig 2. 2. X+X+X=3X Here we see that if you add numbers 3 times to itself it will not give u the same answer as if you multiply it 3 times to itself So X+X+X is not equal to X×X×X The same way 3+3+3 is not equal to 3×3×3 Fig 3. 3.  Y 1 = Y Fig 4. 4. Y0 = 1 Fig 5. Eg. a 1  = a. Any number raised to the  power of one equals the number itself. For any number a, except 0, a0 =  1 . Any number raised to the  power of zero, except zero, equals  one . 5. X×X ≠ X+X To solve  x multiplied  by  x , try to observe...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss some more elementry formulae to find the Area/volume and perimeter of 5 more shapes After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's begin 1a. Area of a parallelogram  = b×h (b=base, h=height) 1b. Perimeter of a parallelogram = Sides(a+a+b+b) =2a+2b =2(a+b) Fig 2. 2a. Area of a rhombus= There area several ways of finding the area of a rhombus 2ai. Area of rhombus with length of diagonals= (d1*d2)/2, * = × Fig 3. 2aii. Area of a rhombus with base and height = b×h Fig 4. 2b. Perimeter of a rhombus = sum of the lenght of the rhombus =l+l+l+l =4L Fig 5. 3a. Area of a kite when both diagonals are given= (d1×d2)/2 Fig 6. 3b. Perimeter of a kite = a+a+b+b = 2a+2b =2(a+b) Fig 7. 4a. Volume of a sphere = 4/3πr3 4b. Surface area of sphere =4πr² Fig 8. 5. Volume of a Cylinder = πr²h Fig 9. That's all for the day GREATMINDS💡 JOIN US NEXT TIME FOR WAIT FOR IT MORE SHAPE...

So today on MATHSPEDIA we shall discuss some elementry Formulae to find the Area and perimeter of 5 shapes After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's start 1a.  Area of a square = L×L= L square Where L= Length This is so because a square has all it's sides and angles equal 1b.  Perimeter of a square = L+L+L+L =4×L =4L Fig 2. 2a.  Area of a rectangle= L×B(L=length,B= breadth) 2b.  Perimeter of a rectangle= L+L+B+B                 =2L+2B                                               =2(L+B) 3a.  Area of a right angled triangle= 1/2×b×h (b=base, h=height) 3b.  Perimeter of a triangle= Sides a+b+c Fig 3. 4.  The area and circumference of a circle will be shown below👇: Fig 4. This image above👆 explains the circumference of a circle  Fig 5. The image above👆 shows the area and circumference of a circle. Fig 6. The image...
