1 = +1; 5 = +5; 177 = +177….any unwritten value number gives a + value

1 = 1/1 or 5/5  or 71/71……when numerator has the same value as denominator

4 = 4/1; 17 = 17/1….any number when converted to fraction will have 1 as their denominator

5^2 = 5² = 5 x 5…..^ indicates the power of

2/5 = 2 ÷ 5

ab = a.b = a x b

1/2 = 0.5

50% = 50/100 = 1/2 = 0.5

√x = ²√x = x^ 1/2

³√x = x^1/3

(³√x)² = x^2/3

x^(-2) = 1/x^2

x^0 = 1….any number in the power of 0 will gives a value of 1

x^1 = x….any number in the power of 1 will gives a value of the number itself

a^2 x a^3 = a^(2 + 3) = a^5

a^5 ÷ a^2 = a^(5-2) = a^3

4 – 2 = -2 + 4

5 x 3 = 3 x 5

a(m + n) = am + an

a(m – n) = am – an

-(m – n) = – 1(m – n) = – m + n
