for the first one -2 (-2)(-2) = - 8. Square - 4 and you get 16
- 8 + 16 = 8
3 - 25+18 = - 4
8 / -4 = - 2

=( -8 +16)/(3-25+18)
= 8/-4 = -2

= (-8 +16)/(3 - 25 + 18)
= -8/-4
= 2

-2^3= -8
-4^2= 16
+5^2= 25
-3(-6)= 18
substitute all this in ur question
-8+16
------------
3-25+18
8

(2)^2=(-20(-2)(-2)=-8
(-4)^2=(-4)(-4)=16
5^2=25
(-3)(-6)=18
(-8+16) / (3-25+18)
8/-4=-2

to income Math actual and actual keep in mind it, you may desire to familiarize first with the numbers and with the elementary operations --- upload, subtr, mult, div, etc. you may desire to memorize (this could be a could desire to) the multiplication table from (first step) 1x1, 1x2, 1x3, ... 12x1, 12x2, as much as twelve x12, then later (next step) as much as twenty x 20. Memorization is important no longer in straight forward terms for multiplication, branch, addition, subtraction yet additionally for paying for the sq. of the huge form and sq. root, now and returned cube of the huge form and cube root. different issues in Math are gaining knowledge of to persist with the guidelines as in arithmetic, algebra, geometry, trigonometry, calculus, etc. Memorization different than for clean understanding the techniques are againj could desire to. you besides could could desire to comprehend the problem to be solved. With those courses, issues will replace into immediately basic in Math.
