Question

to make $48 + 34$ easier to solve, lou decides to first add on from 48 to get to the next ten.
add on to get to 50.
$48 + \square = 50$
now, find the sum.
$48 + 34$
$= 48 + (2 + 32)$
$= (48 + 2) + 32$
$= \square$

Explanation:

Step1: Split 34 into 2+32

$34 = 2 + 32$

Step2: Rewrite the sum with split term

$48 + 34 = 48 + (2 + 32)$

Step3: Regroup terms to make a ten

$=(48 + 2) + 32$

Step4: Calculate first pair

$48 + 2 = 50$

Step5: Add remaining term

$50 + 32 = 82$

Answer:

82
