Math and Arithmetic

Perimeter is NOT squared.

Squaring calculated the area inside the perimeter.

The perimeter is the addition of the lines that form the edge/perimeter.

For the general straight line eq'n ; y = mx + c

'm' is the slope

'c' is the y-intercept.

For a pair of point on a graph ( x1,y1,) & ( x2,y2)

Then

m = {y1 - y2) / ( x1 -x2)

Note the 'y' co-ords go on the top , and the 'x' co-ods go on the botton.

Note also The position of first term '1' and the second '2' term. Otherwise you will have a wrongly calculated slope/gradient.

Wrong!!!!

Any number ends in '0' is divisible by '10'

Any number ending in '5', or '0' is divisible by '5'.

e.g.

1,000,000 ( one million) is divisible by both '5' & '10 / The respective answers are '- 200,000' and ,100,000;.

A number such as ' 1,000,001'. is NEITHER divisible by '5' NOR '10'.

Since 15324 is an even number ( ends in 0,2,4,6,8) it will divide by '2'

Hence

2. 15324

2)7662 Similarly

3)3831 Since 3831 is an ODD number we try '3' ; the next prime number.

1277 is a prime number.

Hence factors of 15324 are 2,2,3,1277

This question is rather poorly described. It could mean ;-

#1 ; (120/24) x 5

or

#2 ; 120/(24 x5)

Because the answers are different.

#1 ; (120/24) X 5 = 5 x 5 = 25

#2 ; 120/(24x 5) = 120/120 = 1

So you need to be a clearer in your question.

To simplify 76/100, you would first find the greatest common factor (GCF) of the numerator (76) and the denominator (100), which is 4. Dividing both numbers by 4 gives you 19/25. Therefore, the simplest form of 76/100 is 19/25.

Yes; but it's probably not hard in the way most people think.

A Level Maths is a big step up from GCSE because it focuses much more on problem-solving than memorising methods. Topics like calculus, trigonometry, logarithms, mechanics, and statistics all build on each other, so if you fall behind in one area, later topics become much tougher.

That said, thousands of students achieve high grades every year because consistent practice matters far more than natural talent. Maths also remains the most popular A-Level subject in the UK, which shows that while it's challenging, it's also highly valued by students and universities.

What helped me most was:

Practising past papers every week.

Reviewing mistakes instead of just checking answers.

Learning the why behind each method.

Following a structured revision plan rather than revising random topics.

If you're studying independently, resources like Exam.Tips, PMT, and official exam board materials are all useful for building a more organised revision routine.

So yes, A Level Maths is difficult—but it's absolutely manageable with consistent practice and the right approach.

48 x 10 = 480

By the end of 1878, 38 states had been admitted to the Union. The next twelve, in order, were North Dakota, South Dakota, Montana, Washington, Idaho, Wyoming, Utah, Oklahoma, New Mexico, Arizona, Alaska and Hawaii.

In terms of money, 3.5k represents 3,500 units of a particular currency. The "k" in this context stands for "thousand," so 3.5k is shorthand for 3,500. Therefore, if we are talking about US dollars, 3.5k would be equivalent to $3,500.

That is an APPROXIMATE value of pi. The exact value cannot be calculated since pi is a transcendental number - a special kind of irrational number. It has an infinite decimal representation with no recurring pattern. That would be true in any base - binary, octal, or another base (other than pi itself, or a power of pi).

It is still being calculated.

Supa-Dupa computers have calculated 'pi' to at least 50 billion places and still going.

The ancients would have calculated 'pi' to at least 10 places. or more.

estimates for pi are 3.14, 3.1416, 3.14159 or 22/7

They are all approximations.

pi is an irrational number, which means it cannot be converted to a ratio/quotient.

The Classical Greek mathematician , Archimedes, calculated 'pi' to a degrees of estimation.

i will give you a very smart trick to find the ten percent of any number in just 2 seconds.

See , 10 % 0f 500 = 50.0

10 % of 3500 = 350.0

you have to put a decimal just after the unit digit's place and you are done,

So for 10 % 0f 110,000 = 11000.0

It's only called the difference if it is the answer to a subtraction. That is because that is the "difference" between the two numbers.

For example: 5 - 2 = 3.

2 is 3 numbers away from 5.

It's hard to explain, but hope I helped.

The highest prime number after '11' is infinitely high!!! To the point no one knows it!!!!!

However, I think you mean ' The next higher prime number after '11'? , Which is '13'.

3x = x + 10

Subtract 'x' from both sides.

2x = 10

divide both sides by '2'

x = 5

Shapes with lines of symmetry are; -

Squares, Rectangles, Rhombus, Symmetric Trapezium, Kite, Circle.

Square; Top to bottom, Side to side, Corner to corner.

Rectangle ; Top to bottom, Side to side

Rhombus, Corner to corner.

Symmetric Trapezium; to to bottom, between parallel lines

Kite ; largest angle to smallest angle

Circle ; Any radii.

A symetry line is like a mirror line, if you put it in the middle of something, the other side will have to be the same thing, flipped. if you take the letter V, you can put a vertical symetry line in the middle of it, and both sides will be exactally the same, but just flipped.

'sf' means 'significant figures'.

You then specify the number of significnt figures.

e.g. 123456. to 3 s.f. is 123000

196.7 is already at one d.p.
