EASY WAYS TO SOLVE MATHEMATIC
PROBLEM
QUICK COUNT
1. If P =
17
19
+
21
24
+
33
36
, then Q =
17
19
+
54
36
+
33
24
. So…
Answer
First, we sort denominators of numbers to make two
equations same as another
P =
17
19
+
21
24
+
33
36
Q =
17
19
+
33
24
+
54
36
After that, we know that numerators of Q is bigger than P
So, we can decide that P<Q

=
Answer
Take a look at
1
8
+
(
1
8
:1
8
)
+
1

=
Because two fractional numbers inside the bracket are the same,
so the result is always 1.
Two fractional numbers outside the bracket are also the same, we
can change form equation

1
8
→ 2 x
1
8
→
2
8
So The Final Result is
1 +

3. `(12x30)2
−
(118+241)2 =
Answer
(12x30)2
−
(118+241)2 =(360)2
−
(359)
Use this principle
a2
−
b2 = (a+b)(a-b)
(360)2
−
(359)2 = (360+359)(360
−
359)
= (719)(1)
