Distributive law ✔️✔️Correct Ans-a(b + c) = ab + ac
Fractions and Decimals ✔️✔️Correct Ans-x/y
x numerator
y denominator
1/100 + 4/100 = 5/100
1/3 + 1/2 = 2*1/2*3 + 3*1/3*2= 2/6 + 3/6 = 5/6
4/5 * 5/6 = 20/30
2//3 = 2/3 * 3/4 = 6/12 = 1/2
2 3/4 = 11/4
1/8<1/2
3/5= .6
.0099
.01
.01 is larger
Exponents ✔️✔️Correct Ans-2^3= 2*2*2= 8
MADSPM (exponents) ✔️✔️Correct Ans-Multiply-> add 2^3 * 2^5= 2^(3+5)= 2^8
Divide-> subtract 2^5/2^3 = 2^(5-3)= 2^2
Power-> multiply (2^3)^4= 2^(3*4) = 2^12
