Decimals are a way to write fractions and mixed numbers without using a numerator and denominator. Because the denominator isn’t written, it may be difficult at first to compare the values of two or more decimals, particularly when they have a different number of digits after the decimal point. When comparing two (or more) decimals, you are trying to find if they are less than <,

Vectors are physical quantities that consist of a magnitude as well as a direction (for example velocity, acceleration, and displacement), as opposed to scalars, which consist of magnitude only (for example speed, distance, or energy). While scalars can be added by adding their magnitudes (for example 5 kJ of work plus 6kJ of work equals 11kJ of work), vectors are slightly more
