Rojina worked out $90$ sums in one day. Shefali did $65$ sums at the same time. Let's find what percentage of sums Rojina did more than Shefali. Let's find the per­centage of sums Shefali did less than Rojina during that period of time.

Let's colour $10\%$ of the squares red and $40\%$ of square yellow in the squared figure given below. 

Let's verify on the number line and put $\left[=/\ne \right]$ in the blank.

$\left(-5\right)+\left(-3\right)$ _____ $\left(-3\right)+\left(-5\right)$

Let's verify on the number line and put $\left[=/\ne \right]$ in the blank.

$\left(+7\right)+\left(+2\right)$ _____ $\left(+2\right)+\left(+7\right)$

Find the value of $\left(-3\right)-\left(+4\right)$ on the number line.

Let's verify on the number line and put $\left[=/\ne \right]$ in the blank.

$\left(+4\right)-\left(-3\right)$ _____ $\left(-3\right)-\left(+4\right)$

Let's verify on the number line and put $\left[=/\ne \right]$ in the blank.
