Am I Good At Math For My Age?

The result of 12×412×4 is 48. Multiplication is a basic arithmetic operation where you combine a number (in this case, 12) with another number (4) a certain number of times (in this case, once). The product, or result, is the total of these repeated additions. In this instance, 12 multiplied by 4 gives you 48.

When you subtract 49 from 100, you are finding the difference between the two numbers. Mathematically, it can be expressed as:

100−49=51

So, the result of 100−49 is 51. This means that if you take away 49 from 100, you are left with 51. Subtraction is an essential arithmetic operation used to determine the remaining quantity or the difference between two values.

When you add 100 to 10001, you are performing a basic arithmetic operation to find the total or sum of these two numbers. Mathematically, it can be expressed as:



100+10001=10101

So, the result of the addition is 10101. This means that if you combine 100 and 10001, you get a total of 10101.

To find the cost of the speaker, you can subtract the cost of the DVD player from the total amount paid.



Cost of Speaker = Total Amount Paid - Cost of DVD Player



Given that the total amount paid is £29.75 and the cost of the DVD player is £17.99:



Cost of Speaker = £29.75 - £17.99 



Cost of Speaker} = £11.76



Therefore, the cost of the speaker was £11.76.

When you subtract 275 from 675, you are finding the difference between these two numbers. Mathematically, it can be expressed as:

675−275=400

So, the result of 675−275 is 400. This means that if you take away 275 from 675, you are left with 400.

The result of (-3) times (-5) times (2)) is (30). 



When you multiply two negative numbers, the result is positive. Therefore, (-3) times (-5) is (15), and then (15 times 2) equals (30).

To find the value of A in the equation A/6 you can multiply both sides of the equation by 6 to isolate A:



 A = 30 times 6 



A = 180 



Therefore, the value of A is 180.

To simplify the fraction 100/225 to its lowest form, you can find the greatest common factor (GCF) of the numerator (100) and the denominator (225) and then divide both by that factor.



The GCF of 100 and 225 is 25.



So, dividing both the numerator and denominator by 25:



100/225 = 4/9



Therefore, 100/225 in its lowest form is 4/9

To divide fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.

1/4 divided by 2/5 = 1/4 x 5/2

 

Which gives 5/8
